The mirrorless transformation is going full bore. These amazing computerized cameras pack enormous picture sensors into reduced bodies, offering the absolute best picture and video quality available with less mass than a DSLR. Also, as the focal point choices keep on growing, going mirrorless bodes well now than any time in recent memory. Beneath we separate the best mirrorless-tradable focal point frameworks of 2019, from full-outline models for experts to driving spending choices. Almost the majority of the huge brands are spoken to, including Sony, Panasonic, Fujifilm, Canon, and Nikon. For more foundation data, see our mirrorless camera examination table and purchasing counsel underneath the picks.

Best Overall Mirrorless Camera
1. Sony Alpha a7R III ($2,498)
Sensor size: 864 sq. mm
Megapixels: 42.4
Weight: 23.2 oz. 
What we like: The whole package in a mirrorless camera for both stills and videos.
What we don't: One of the most expensive cameras on this list, and lenses aren't cheap either.
Lenses: 10 Great Sony FE (Full Frame) Lenses

Sony has driven the full-outline mirrorless market for quite a long time, and the Alpha a7R III still is at the highest point of the load for 2019 (at any rate until the new IV is discharged). This smooth camera essentially does everything: you get 42.4 megapixels of goals, magnificent self-adjust and following, in-self-perception adjustment, 4K video, and climate fixing—we could continue forever. Critically, this camera likewise got an overhauled battery type (FZ100) from the more established a7R II, which improved things greatly (no all the more bearing a sack of additional batteries). For everything from still photography to recordings, it's the best all-around mirrorless camera available.

What are the deficiencies of the Sony a7R III? In spite of the ongoing drop in value, it's as yet held for picture takers with greater spending plans, and GM focal points aren't actually modest either. For the individuals who need to spend less, Sony makes the a7 III (no "R") beneath, which has less megapixels at 24.2 yet brags numerous similar highlights for fundamentally less. It's important that Sony's full-outline rivalry is expanding: a year ago, Nikon discharged its profoundly foreseen Z6 and Z7 mirrorless cameras, and Canon presently has the EOS R. As far as the new Sony a7R IV, that camera hops to an incredible 61 megapixels and starts sending this fall.

Best Budget Mirrorless Camera
2. Panasonic Lumix GX85 ($598 with 12-32mm and 45-150mm lenses)
Sensor size: 225 sq. mm
Megapixels: 16
Weight: 15 oz.
What we like: A tremendous value for a mirrorless camera with two lenses.
What we don't: Fewer megapixels than the Sony a6000 below, one of its primary competitors.

Over the many years that this article has been in existence, the Panasonic GX85 kit is one of the best values we’ve seen. For just under $600, you get a compact mirrorless camera from a leading brand that features 4K video, in-body image stabilization, shooting speeds of up to 10 fps, and built-in Wi-Fi. Perhaps most impressively, the GX85 kit includes two lenses: a 12-32mm and 45-150mm, giving you a nice range of focal length coverage from wide angle to telephoto. We especially like the low-profile size of the 12-32mm, which weighs just 2.5 ounces and is a great walk-around lens for travel and everyday use.

In terms of competitors, the Sony Alpha a6000 below is an old favorite and currently $548 with one lens. The Sony has more megapixels at 24.3 and a larger APS-C image sensor, but lacks modern features like 4K, built-in image stabilization, and touchscreen functionality, all of which we think are fairly important. All in all, both are excellent mirrorless cameras at attractive price points, so your decision may come down to brand and lens preference. In this case, we think the two-lens bundle and more complete feature set of the Panasonic GX85 are hard to pass up.

Best Mirrorless Camera for Video
3. Panasonic Lumix GH5 ($1,498)
Panasonic Lumix GH5 cameraSensor size: 225 sq. mm
Megapixels: 20.3
Weight: 25.6 oz.
What we like: Premium video quality and feature set. 
What we don't: Less of an all-rounder than the Panasonic G9 below.
Lenses: 10 Great Micro Four Thirds Lenses

Among its mirrorless peers, Panasonic has had a leg up in the video department for years, and the GH5 is their flagship camera for this purpose. It boasts 4K video speeds that can rival any pro DSLR, a highly advanced autofocus system, built-in image stabilization, and a tough, weather-sealed body that can handle long shoots in a variety of conditions. You also get 10-Bit recording, a full HDMI socket, and a host of advanced functionality options. This substantial feature set makes the GH5 a leading choice among professional video shooters looking for a compact set-up. 

Keep in mind that even though the Panasonic Lumix GH5 is ranked here due to its standout video prowess, it’s not necessarily the best all-rounder. For example, Panasonic's own G9 below is newer, cheaper, better suited for stills, and still very capable for video. Those who want a mirrorless camera strictly for video will appreciate the features and functionality of the GH5, but in our opinion, the G9 is the more versatile option overall. And for a full-frame competitor to the GH5, see the video-centric Sony Alpha a7S II.

Best of the Rest
4. Fujifilm X-T3 ($1,499)
Fujifilm X-T3 mirrorless cameraSensor size: 368 sq. mm
Megapixels: 26.1
Weight: 19 oz.
What we like: Top-tier image and build quality; impressive feature set. 
What we don't: No in-body image stabilization and short battery life.
Lenses: 10 Great Fujifilm X-Mount Lenses

We'll start by saying that we love Fujifilm mirrorless cameras. They are sleek, well-built, have the truest color rendition of any brand, and the Fujinon lens collection is superb. For uses like travel, portraits, and street photography, you'd be hard pressed to find a better camera for your money. At the same time, the X-T3 does not have a full-frame image sensor like the Sony Alpha series, Nikon's Z6 and Z7, and the Canon EOS R below. Many professionals stick exclusively to full frame and rightfully so, but the Fujifilm X-T3 is a powerhouse camera in its own right that should make even the most discerning photographers happy.

The X-T3 was released at the end of last year, so what changed on this camera? The simple answer is that just about everything improved: Fujifilm bumped up the megapixel count to 26.1, made major improvements to the autofocus system across the board, and added touch sensitivity to the rear LCD (we love the touch focus feature in particular). You also get a faster burst rate at 11 frames per second, a new processor that helps everything function quickly and smoothly, and video features that now are more competitive with the field. The two biggest downsides of the X-T3 are the lack of in-body image stabilization and the relatively short battery life, but those are small hurdles to overcome for an otherwise outstanding mirrorless camera.
See the Fujifilm X-T3

5. Sony Alpha a6000 ($548 with 16-50mm lens)
Sony a6000 mirrorless cameraSensor size: 366 sq. mm
Megapixels: 24.3
Weight: 12.2 oz.
What we like: A tremendous value.
What we don't: Lacks 4K video and other modern features.
Lenses: 11 Great Sony E-Mount Lenses

The Sony a6000 is getting a little long in the tooth, but remains one of the more popular mirrorless cameras and for good reason. For around $550 with a kit lens, you get a 24.3-megapixel APS-C image sensor, fast shooting at up to 11 frames per second, built-in Wi-Fi, and a total weight of just over 12 ounces. It’s true that this camera line has improved significantly over the years, including with the newer a6400 and a6500, but those models are nearly double the price or more. If you’re looking to go mirrorless without breaking the bank, the a6000 is a nice choice.

What do you give up by going with the Sony a6000? The camera lacks modern features like 4K video, in-body image stabilization, and weather resistance, plus the autofocus isn’t nearly as advanced as the newer models. On the flip side, the a6000 has the same resolution, build quality, and easy-to-use functionality that Sony has built its reputation on. For those looking to save even more, the entry-level Sony a5100 is slightly less capable than the a6000—it has no electronic viewfinder, for example—but is only around $450 with a kit lens. And for another fun budget option from a different brand, see the Canon EOS M50 below.
See the Sony Alpha a6000

6. Canon EOS R ($1,999)
Canon EOS R mirrorless cameraSensor size: 864 sq. mm
Megapixels: 30.3
Weight: 20.5 oz. 
What we like: More megapixels than the Nikon Z6 or Sony a7 III.
What we don't: Lacks in-body image stabilization.

Sony was the only game in town in the pro mirrorless market for years, while Canon fans waited patiently for their time. New for last year, the EOS R is a very strong start and has generated a lot of excitement. You get 30.3 megapixels of full-frame resolution (more than the Nikon Z6 or Sony a7 III), a robust autofocus system, and fast buffering for action photography and video. Perhaps most importantly—and the reason many people go mirrorless—the Canon EOS R weighs just 20.5 ounces and has a much smaller form factor than its DSLR counterparts. The Canon 5D Mark IV, for example, weighs 28.2 ounces and is significantly larger in size.

It's a tough call between the three brands now competing for the attention of professionals and enthusiasts looking to go mirrorless, and in all honesty, the choice often comes down to your existing lens collection. It's worth noting that Canon's EF to EOS R adapter (offered with the camera for only $99 more) is getting high marks in terms of performance with EF lenses, and you also can use EF-S lenses and the camera has a nifty automatic crop mode. However, we would like to see Canon add in-body image stabilization to the mix, which is the major downside of this camera, but that very well may happen sooner rather than later. 
See the Canon EOS R

7. Fujifilm X-T30 ($1,299 with 18-55mm lens)
Fujifilm X-T30 mirrorless cameraSensor size: 368 sq. mm
Megapixels: 26.1
Weight: 13.5 oz. 
What we like: The same sensor and image processor as the pricier X-T3 above.
What we don't: No weather sealing.
Lenses: 10 Great Fujifilm X-Mount Lenses

Fujifilm's flagship mirrorless camera is the X-T3 above, but the new X-T30 might be even more impressive for the price. Released in spring of 2019, you get the same image sensor as the X-T3 in a smaller package and at a cheaper price point. What features do you lose out on? The X-T30 is not weather sealed, has an inferior viewfinder, a lower resolution LCD screen, and more limited 4K video speeds. But image quality is largely the same, and we love the X-T30 for travel and everyday use.

Keep in mind that the Fujifilm X-T30 is behind the field in some ways. As mentioned above, it's not weather sealed (comparable mirrorless cameras like the Sony a6300 and Olympus OM-D E-M5 Mark II are). And Fujifilm video quality still is inferior to brands like Sony and Panasonic, although it has improved significantly over the past few years. But for those who shoot mostly still photography and want premium image quality in a compact package, the X-T30 is an excellent mirrorless camera at a good price.
See the Fujifilm X-T30

8. Panasonic Lumix DC-G9 ($1,198)
Panasonic Lumic DC-G9 mirrorless cameraSensor size: 225 sq. mm
Megapixels: 20.3
Weight: 20.3 oz.
What we like: A highly versatile camera with a wide selection of quality lenses to choose from.
What we don't: Not quite as video capable as the Lumix GH5.
Lenses: 10 Great Micro Four Thirds Lenses

Until the release of the Panasonic G9, the GH5 above was our favorite Micro Four Thirds camera, and it still is for video. While the GH5 prioritizes video and addresses stills later, the G9 does just the opposite, making it a more versatile and practical camera for most people. The G9 still records 4K video at 60p, but also shoots stills at 20 fps while the GH5 only does 12 fps. Another benefit of the G9 is the new USB port that allows you to charge the camera on the go or while in use, helping to ensure that you won't run out of battery during those longer sessions. And given the difference in price and lower weight, the G9 is one of the top Micro Four Thirds cameras on the market.

For those hesitant to buy a Micro Four Thirds camera based on the smaller sensor (more on that in our buying advice below), Panasonic did include a high resolution mode on the G9. The feature is intended mostly for landscape and architecture photographers, and it combines 8 photographs into a single and massive 80-megapixel file. While this can be highly beneficial for static subjects, those interested in shooting movement may find this feature obsolete. Either way, it's a nice touch on a very well-rounded mirrorless camera.
See the Panasonic Lumix DC-G9

9. Canon EOS M50 ($649 with 15-45mm lens)
Canon EOS M50 mirrorless cameraSensor size: 332 sq. mm
Megapixels: 24.1
Weight: 13.6 oz.
What we like: Added a much-needed electronic viewfinder.
What we don't: Massive crop in 4K mode.

Canon mirrorless cameras still aren't on par with the likes of Sony or Fujifilm, but they are gaining ground with the M50. This popular and attractively-priced mirrorless camera improves upon the older Canon M5 by adding 4K video capability, better autofocus, and a faster image processor. You also get a touchscreen LCD, which has a "Touch and Drag AF" feature that is great for making quick adjustments on the fly. Importantly, the M50 also adds an electronic viewfinder, which the M100 below lacks, and comes in a few hundred dollars cheaper than the M5. All things considered, the M50 is far from perfect but still one of our favorite Canon mirrorless cameras to date.

Canon's release of a 4K-capable mirrorless camera is a bit deceiving, however, as the 4K mode comes with a 2.56x crop. That is pretty substantial and means that if you're shooting 4K video with the 15-45mm lens, you're looking at an equivalent of 28.4-115.2mm (this makes shooting wide-angle video on the M50 nearly impossible). Another notable downside is that the M50 has the shortest battery life of any model on this list, coming in at a mere 235 shots per charge. Unless you're only interested in brief sessions, you'll likely need to carry multiple batteries.
See the Canon EOS M50

10. Olympus OM-D E-M10 Mark III ($599 with 14-42mm lens)
Olympus OM-D E-M10 Mark III cameraSensor size: 228 sq. mm
Megapixels: 16.1
Weight: 14.5 oz. 
What we like: Compact in size yet packed with features.
What we don't: Low on megapixels.
Lenses: 10 Great Micro Four Thirds Lenses

Olympus has been very competitive in the mirrorless market for years, but consumers have felt the squeeze when considering high-end models like the E-M1 Mark II. Enter the E-M10 Mark III, a more affordable option that offers Olympus's signature image and video quality for around $600 with a kit lens. New to the Mark III is 4K video, superior image stabilization, more autofocus points, and a more approachable menu system and user experience overall. Factor in the vast collection of Micro Four Thirds lenses, and you have a highly versatile travel camera with a small form factor.

We hemmed and hawed about whether to include the Mark III or Mark II here—newer isn't always better when you take price into consideration. The older model is about $100 cheaper with the same kit lens, and unless you frequently shoot video, none of the upgrades are particularly groundbreaking. But we do like the sum of the changes, which is why we give the new E-M10 Mark III the edge.
See the Olympus OM-D E-M10 Mark III

11. Nikon Z6 ($1,797)
Nikon Z6 mirrorless cameraSensor size: 864 sq. mm
Megapixels: 24.5
Weight: 20.6 oz.
What we like: A full-frame mirrorless camera from Nikon for less than $2,000. 
What we don't: Autofocus could be improved and the Z-mount lens selection is limited.

Nikon's Z6 mirrorless camera received a lot of hype when released and rightfully so. It checks almost all of the boxes that people were hoping for: a full-frame image sensor, in-body image stabilization, fast continuous shooting at 12 frames per second, a wide range of video speeds, and a tough, weather-sealed body that is built to Nikon's lofty standards. Plus, with a relatively small form factor and weight of 20.6 ounces, you get much better portability than full-frame DSLRs like the Nikon D750 (26.5 ounces) and hefty D850 (32.3 ounces). And although we included the Z6 here, Nikon released two mirrorless cameras to start: the Z7 offers 45.7 megapixels of resolution and more in the way of advanced features for a whopping $3,600.

Where does the Nikon Z6 fall short? The autofocus system is solid overall but lags behind the competition in certain aspects, and subject tracking and refocusing in particular. And in choosing between this camera and comparable Sony options, lens selection made the difference for us. The first four Z-mount lenses are good but not great, Sony is years ahead in this regard, and even Canon's RF initial offerings have faster apertures. But if you already own Nikon full-frame lenses, the Z6 is sold with an FTZ adapter that makes your FX glass fully compatible.
See the Nikon Z6

12. Sony Alpha a6500 ($1,198)
Sony a6500 mirrorless cameraSensor size: 366 sq. mm
Megapixels: 24.2
Weight: 16 oz.
What we like: Compact yet packs a serious punch.
What we don't: Pricey and short battery life.
Lenses: 11 Great Sony E-Mount Lenses

Just when you thought Sony couldn't keep innovating at the same blistering pace, they released the a6500 only months after its predecessor, the a6300. Why the quick upgrade? Both are solid mid-range mirrorless cameras that offer 4K video, advanced autofocus, and weather resistant bodies that are well suited for the outdoors. But the a6500 adds in-body image stabilization and touchscreen functionality to the rear LCD, both of which are useful changes. With a $350 increase in price over the a6300, the choice mostly comes down to budget.

It's worth noting that the a6500 didn't receive the same battery update as Sony's latest Alpha a7 cameras, so you'll still be battling a notoriously short battery life. And as is the case with full-frame cameras like the older Sony a7R II, some users have reported overheating when shooting 4K video on the a6500 for extended periods of time. This means that the Panasonic GH5 and G9 above still beat Sony for dedicated videographers, but the a6500 is a terrific all-around mirrorless option nevertheless.
See the Sony Alpha a6500

13. Sony Alpha a7 III ($1,998)
Sony Alpha a7 III mirrorless cameraSensor size: 864 sq. mm
Megapixels: 24.2
Weight: 22.9 oz.
What we like: A more affordable alternative to the Sony a7R III.
What we don't: Fewer megapixels.
Lenses: 10 Great Sony FE (Full Frame) Lenses

For those hoping to go full-frame without breaking the bank, there is a lot to like about the Sony Alpha a7 III. Most importantly, the camera incorporates many of the same features as the more expensive a7R III above (our top mirrorless pick) including an advanced autofocus system, fast burst rate of 10 fps, 4K video functionality, and more than double the battery life of the older Alpha a7 II. But with a price tag of less than $2,000, the a7 III is an approachable way to access to Sony's full-frame mirrorless lineup without compromising a ton in the way of performance.

What are the shortcomings of the Sony a7 III? Most notably, the camera has a 24.2-megapixel sensor, which is a considerable drop from the 42.4 megapixels of the a7R III. However, for many people and uses, this is ample resolution, can create outstanding images and videos, and won't take up as much space on your hard drives. And compared to the new full-frame Nikon Z6 above, the Sony has superior autofocus, weighs slightly less, and has many more native lens options. 
See the Sony Alpha a7 III

14. Olympus OM-D E-M1 Mark II ($1,499)
Olympus OM-D E-M1 Mark II mirrorless cameraSensor size: 226 sq. mm
Megapixels: 20.3
Weight: 20.3 oz.
What we like: Loaded with features and functionality.
What we don't: Too expensive for our tastes, and particularly if you don't shoot action.
Lenses: 10 Great Micro Four Thirds Lenses

For those who love the Micro Four Thirds system and have money to spend, the OM-D E-M1 Mark II is a very impressive mirrorless camera that shows just how far this technology has come. This camera has pretty much all the bells and whistles that enthusiasts want: in-body image stabilization, fast burst rates for action photography, 4K video, and a weather-sealed magnesium alloy body that is great for shooting outdoors in tough conditions. For everything from travel to landscapes, this E-M1 Mark II does it all.

Our biggest issue with the OM-D E-M1 Mark II is the cost. At $1,500 for the camera body alone, it's more expensive than most other crop sensor mirrorless cameras on the list as well as popular full-frame DSLRs like the Nikon D750 or Canon 6D. It's even roughly the same price as the Nikon D500, another action specialist. And although the Olympus boasts impressive features and some of the best in-camera stabilization of any mirrorless camera, the Panasonic G9 above is our preferred Micro Four Thirds option.
See the Olympus OM-D E-M1 Mark II

15. Panasonic Lumix G85 ($698 with a 16-50mm kit lens)
Panasonic Lumix G85 mirrorless cameraSensor size: 224 sq. mm
Megapixels: 16
Weight: 14.6 oz.
What we like: 4K video and high fun factor. 
What we don't: Lower resolution than most cameras on this list.
Lenses: 10 Great Micro Four Thirds Lenses

The Panasonic G85 is a tweener: it's not a true enthusiast mirrorless camera, but definitely shouldn't be categorized as entry level either. And if you compare it to a premium point-and-shoot like the Sony RX100 V that is similar in cost, we would take the G85 in a heartbeat. Simply put, if you're looking for quality photos and videos but don't need the features or resolution of the G9 above, give the G85 a serious look.

Panasonic is known for video, so it's no surprise that the G85 shoots 4K and is darn good at it. You also get fast continuous shooting, good autofocus for the price, and new to this model are weather sealing and built-in image stabilization. Compared to cameras like the Canon M50 or Sony a6000, you don't get quite the resolution with the smaller image sensor and fewer megapixels, but the 4K video, sleek design, and access to good lenses all are big selling points. For video shooters shopping in the sub-$700 price range, the G85 may be the ticket.
See the Panasonic Lumix G85

16. Canon EOS M100 ($449 with 15-45mm lens)
Canon EOS M100 mirrorless cameraSensor size: 332 sq. mm
Megapixels: 24.2
Weight: 10.7 oz. 
What we like: Bargain basement price and low weight.
What we don't: No 4K video and limited lens options.

At just $450 with a 15-45mm kit lens (many advanced point-and-shoots cost more) the M100 is another nice mirrorless option from Canon and a great value. In terms of specs, you get 24.2 megapixels of resolution, decent autofocus, a burst rate of 6.1 fps (faster than Canon's entry-level DSLRs), and Bluetooth connectivity. And at just 10.7 ounces for the camera body, the M100 delivers a lot of functionality in a small package.

Keep in mind that the M100 does not have a viewfinder, meaning that you'll have to line up your photos and videos via the rear LCD, nor does it shoot 4K video like the M50 above. And although Canon's collection of EF-M lenses is growing and some third-party manufacturers have jumped into the mix, you won't find pro-grade options like you do with Fujifilm or Micro Four Thirds. But for those new to mirrorless or familiar with Canon systems, the M100 is an inexpensive camera that should get the job done. 
See the Canon EOS M100

17. Panasonic Lumix G7 ($498 with 14-42mm lens)
Panasonic Lumix G7 mirrorless cameraSensor size: 224 sq. mm
Megapixels: 16
Weight: 14.6 oz.
What we like: 4K video and an EVF at a good price point. 
What we don't: Fewer megapixels than newer entry-level models.
Lenses: 10 Great Micro Four Thirds Lenses

Good news for aspiring videographers and fans of Panasonic: you don't have to spend $1,000 for your mirrorless camera (or anything close to it). The G7 was released a few years ago and therefore isn't new, but is a solid value at less than $500 with a kit lens. In fact, it's one of the cheapest ways to access 4K video in 2019, plus you get an electronic viewfinder. Despite the drop in resolution from Sony's and Canon's latest entry-level models, Panasonic does a lot of things right including excellent video quality and features.

What do you sacrifice with the Panasonic G7 compared to the pricier G85 above? The G7 does not have built-in image stabilization, which admittedly is very helpful. In addition, the camera is not weather sealed and shoots slower at 7 fps vs. 9 fps on the G85. All of these are notable improvements that make the G85 attractive despite the $300 jump in price. And for those shopping for a Micro Four Thirds camera on a budget, we suggest looking at the Olympus E-M10 Mark III above, which is $300 more but a better camera overall.
See the Panasonic Lumix G7

18. Fujifilm X-A5 ($499 with 14-45mm lens)
Fujifilm X-A5 mirrorless cameraSensor size: 369 sq. mm
Megapixels: 24.2
Weight: 12.7 oz.
What we like: Fujifilm image quality at an entry-level price point.
What we don't: No viewfinder.
Lenses: 10 Great Fujifilm X-Mount Lenses

Despite the lack of a viewfinder, we like the X-A5, Fujifilm's latest release in the entry-level mirrorless market. As is apparent based on the price, this camera is ideal for up-and-comers and those looking for a quality everyday set-up on a budget. Most importantly, you get an APS-C image sensor that can produce quality images for travel and everyday use. For beginners, the camera is packed with easy-to-use presets and automatic shooting modes, and we also like the 14-45mm kit lens, which is well-built, provides a solid focal length range, and is reasonably compact.

In this price range, a close competitor to the Fujifilm X-A5 is the Sony a6000 above (our top budget pick). Both cameras have 24-megapixel APS-C sensors, are similar in weight, and have built-in wireless. The X-A5 does shoot 4K video, but the a6000 has a much faster burst rate and superior autofocus. If you're shooting primarily still photography, the Fujifilm is a nice choice. But for those looking for the more versatile performer for both stills and videos, we give the nod to the Sony.

Choosing a System
We've provided you with a ton of information on specific camera models, but the decision still can feel intimidating. Keep in mind that buying a camera body is an investment into a system and a company. Granted, you're never totally locked into a system, but once you buy a body and start building up your lens collection, you're financially invested and changing can be burdensome. The good news is that all of the brands we've listed are safe bets. All continue to demonstrate a desire to innovate in their own ways. If any of these companies were stagnant it would be easy to rule them out, but with Nikon and Canon emerging (something we discuss below), as well as Sony, Panasonic, Olympus, and Fujifilm not showing any signs of slowing down, you should be safe going with any of them.

The full gamut of mirrorless camera systems

For those of you who hate vague answers and want something a bit more cut and dry, here you go. Keep in mind that these are generalizations and the majority of these systems are well-rounded and should work great for most people's needs. But if we had to break it down based off of trends, here is how we would do it:

Most versatile system for stills and videos: Sony
Bets system for videographers: Panasonic
Best system for street, travel, and portrait photography: Fujifilm
Best compact system for wildlife: Olympus
Sensor size comparison (crop sensor vs. full frame)

 Image Sensor Size
Here at Switchback Travel, we praise image sensor size over megapixels, which has a more significant impact on image quality. The good news is that virtually all mirrorless cameras have large sensors that are similar to most entry-level and mid-range digital SLRs. The two most common sensor types are APS-C (Sony and Fujifilm) and Micro Four Thirds (Olympus and Panasonic). Sony's a7 series of full-frame mirrorless cameras boast full-frame sensors, which is second largest to the medium format sensors found in the Fujifilm GFX 50S and the Hasselblad X1D. Keep in mind that there is some variation between manufacturers and camera models (Canon's APS-C sensor is smaller than Sony's, for example).

Micro Four Thirds (Panasonic and Olympus): 17 x 13mm = 224 - 225 sq. mm
APS-C (Canon): 22.3 x 14.9mm = 332 sq. mm
APS-C (Sony and Fujifilm): 23.5 x 15.6mm = 366 - 369 sq. mm
Full Frame (Sony and Nikon): 36 x 24mm = 864 sq. mm
Medium Format (Fujifilm and Hasselblad): 43.8 x 32.9mm = 1,441 sq. mm

Medium Format
Medium-format cameras long have been a staple for high-end portrait, fashion, and commercial photographers. With incredibly high resolutions due to the extra-large sensors, the images have detail that is impossible to replicate even with a full-frame camera. Unfortunately, these ultra-premium cameras have price tags to match. It's not uncommon to see bodies from Hasselblad and Phase One in the realm of $40,000, so it was pretty exciting when Hasselblad decided to release the X1D, the first mirrorless medium-format camera. At around $6,500, it offers a much more affordable path to medium format for those interested in achieving higher resolutions and better dynamic range. Then came the Fujifilm GFX 50S, another medium-format option at the same price point as the X1D.

At upwards of $10,000 when you factor in lenses, we don't see these cameras as being worth the money for most people. For the majority of folks looking for premium image quality, the 42.4-megapixel Sony a7R III should be more than satisfactory, and Nikon's new Z7 is a whopping 45.7 megapixels. For around half the price, it's hard to argue against going that route. And although the Fujifilm GFX 50S and Hasselblad X1D offer a gateway into a world once reserved for wealthy and elite photographers, we don't see true medium format enthusiasts making the switch.

Megapixels matter, but not nearly as much as camera manufacturers and retailers would lead you to believe. For reference, the crop-sensor cameras on this list have megapixel counts somewhere between 16 and 24.3. Given that the majority of image sensors are either Micro Four Thirds or APS-C, you get fairly comparable image quality across the board. A mirrorless camera like the Sony Alpha a6500 with 24.2 megapixels and an APS-C sensor will produce slightly superior images than a camera like the Olympus OM-D E-M10 Mark III with 16.1 megapixels and a Micro Four Thirds sensor, but they are in the same ballpark. At the professional end of the spectrum, the Sony Alpha a7R III boasts a whopping 42.4 megapixels (plus a full-frame sensor) and the new Nikon Z7 offers even more at 45.7. Remember: it's the combination of sensor size and megapixels that matters.

Key Features on Mirrorless Cameras
Electronic Viewfinder (EVF)
One of the biggest differences between entry-level mirrorless cameras and mid-range and high-end models is the inclusion of an electronic viewfinder, or EVF for short. An electronic viewfinder is a super helpful tool that allows for much greater accuracy in terms of composition and focus. On cameras without a viewfinder, you must align images via the LCD screen on the back much like you would with a point-and-shoot camera or smartphone. Many casual photographers may not mind, but an electronic viewfinder is a highly desirable feature for serious photographers. What is the cutoff for an electronic viewfinder? None of the mirrorless cameras on our list that are less than $600 have an electronic viewfinder, and all above $600 do. To check whether your desired model has an electronic viewfinder, see our comparison table above.

Autofocus Speed and Accuracy
With specs like megapixels and sensor size getting the lion's share of the attention, don't overlook the importance of autofocus in your buying decision. Many cheaper mirrorless cameras cut costs with inferior autofocus, including the number of focus points and types of autofocus (phase detection and contrast detection). There aren't hard-and-fast rules as to what constitutes great autofocus, but good places to start are the number and type of focus points. Multiple focus points help improve accuracy, so the more the better. In addition, contrast detection is slower than phase detection, and cross-type sensors are more accurate than simpler vertical line sensors. Understanding the full complexities of autofocus is worthy of a full article in itself, but in general, you can expect autofocus to be less accurate on cheaper cameras and more accurate on pricier cameras (there is a strong correlation between price and autofocus quality). If a camera is an outlier to this rule, we will let you know in the write-ups above.

In-Body Image Stabilization
An increasingly common feature on new mirrorless cameras in 2019 is in-body image stabilization, which helps offset the effects of camera shake. The names vary by manufacturer, but the technologies are similar: the sensor is able to adjust for small movements, thereby creating photos and videos with less blur. Sony claims that in-body stabilization is worth up to 5.5 stops, and Olympus up to 6.5 stops with image stabilized lenses, which would be impressive if accurate. All in all, we've found this technology to be difficult to quantify but very helpful in doing what it advertises-we have far fewer blurry images from our cameras with image stabilization.
In-camera image stabilization
Many modern mirrorless cameras feature in-body image stabilization

In terms of specific brands and models, Sony's latest Alpha a7R III and a7 III feature in-body image stabilization, as does the crop-sensor Sony Alpha a6500. Most new Olympus cameras do as well, including the E-M10 Mark II, E-M5 Mark II, and E-M10 Mark III. And even Panasonic and Fujifilm are jumping onboard, including the Lumix G9 and X-H1. It's worth noting that the market is right at the tipping point: currently it's mostly high-end and some mid-range cameras that feature in-body image stabilization, but it's starting to trickle down to most new mirrorless cameras regardless of price point.

4K Video
Similar to in-body image stabilization, 4K video once was a rare feature saved for select premium cameras, but it's now common all the way down to entry level. There are a plethora of factors that dictate how good a mirrorless camera is at shooting video, including resolution, autofocus and tracking, available video speeds (these can vary greatly by model), the LCD screen, and video-centric features like 10-Bit recording and HDMI sockets. The good news is that video is getting better and better across the board, and today's mirrorless cameras are leaps and bounds ahead of where they were even a few years ago.

In general, Panasonic is the video hegemon in the mirrorless camera world. Many professionals use the Panasonic Lumix GH5, which is hands down the best mirrorless camera for video. Sony's mirrorless are a close second, including the videographer-focused a7S line, and even the a6500 and previous generations are pretty darn impressive in this regard. Olympus is next in line, and Fujifilm mirrorless cameras are now serviceable in the video department but really excel at still photography.

Built-In Wi-Fi
Plugging your camera into a USB port on a desktop or laptop and uploading photos manually is becoming increasingly unnecessary. Built-in Wi-Fi is a nice perk available on virtually all new mirrorless cameras, allowing you to transfer and upload photos and videos to your device or social media platform directly from the camera (some even offer light editing in-camera). The software and Wi-Fi platforms vary by manufacturer, and some are easier to use and less buggy than others, but we like the option of using Wi-Fi.

One consideration to keep in mind: using Wi-Fi to transfer photos all of the time can eventually take a toll on your camera's processor. Accordingly, we recommend only using the Wi-Fi to transfer images when time is of the essence and you need to make quick selections or edits to your images. Don't be afraid to use Wi-Fi, but if you have a cord handy or can insert the memory card into your computer, doing so will help prolong the life of your camera. 

Weight and Size: Mirrorless vs. DSLRs
Mirrorless cameras get a lot of praise for their compact size and low weight, which makes them attractive for outdoor and travel photographers on the go. It's true that mirrorless cameras weigh less than digital SLRs by forgoing the bulky internal mirror systems (hence the name "mirrorless"), but the difference is not quite as much as you might think. For example, and these aren't exact apples to apples comparisons, the new Sony Alpha a7R III weighs 23.2 ounces for the camera body, while leading full-frame DSLRs like the Nikon D850 (32.3 ounces) and Canon 5D Mark IV (28.2 ounces) both weigh quite a bit more. For a mid-range camera comparison, the Sony Alpha a6500 weighs 16 ounces, while the Canon Rebel T7i is 18.8 ounces and the Nikon D5600 comes in at 16.4 ounces. Clearly, the differences there are less pronounced than the full-frame comparison.

Obviously, focal points likewise should be mulled over. Once more, this all relies upon the frameworks you're contrasting, however we've discovered that our Sony full-outline FE focal points in some cases exceed their Canon or Nikon DSLR partners. Various mid-go mirrorless camera frameworks in the Sony, Fujifilm, and Micro Four Thirds families do have some extremely cool hotcake focal points that weigh alongside nothing, however at the full-outline end of the range, the weight reserve funds regularly is gradual and not great. The bigger point here is that mirrorless cameras are littler and lighter than DSLRs, and structure factor likely is the greatest distinction, yet the weight contrast isn't as much the same number of individuals think. Having said that, given that mirrorless picture quality and focal point accessibility have basically gotten up to speed to DSLRs, we'll take each ounce we can get.

Climate Sealing

Some mid-go and most very good quality mirrorless cameras are climate fixed for included security from the components. Climate fixing changes by maker and model and there aren't all inclusive benchmarks, yet the procedure includes including elastic fixing and lodging the body and around catches to make the camera progressively impervious to dampness and residue (both can be an outright executioner to your gadgets). Calling these cameras weatherproof or waterproof would be a distortion, yet they unquestionably can deal with intense conditions and are prominent among experts who every now and again are out in the field in nasty climate.

For a more profound plunge into this point, we have distributed a total rundown of climate fixed mirrorless cameras, which incorporates mainstream models like the Sony a7 arrangement, Panasonic G9 and GH5, Fujifilm X-T3, Olympus OM-D E-M1 Mark II, and Sony a6500. Olympus and Panasonic cameras specifically are known for fantastic climate fixing, however inasmuch as you're cautious and don't go into too brutal or wet conditions for expanded periods, the majority of the cameras on our climate fixed rundown ought to be satisfactory in keeping the components out.

The Challenge With Dust

On the off chance that you've possessed a mirrorless camera, at that point you realize how troublesome it very well may be to keep the sensor clean. While expelling the mirror from a run of the mill DSLR has numerous advantages, one major drawback is that your sensor is exceptionally powerless against residue, soil, dampness, and some other component holding on to advance inside your camera. On the off chance that you invest energy shooting outside, it's unavoidable that you will in the long run get residue spots on your sensor, yet it happens perceptibly speedier with mirrorless cameras. Furthermore, in spite of the fact that it's absolutely ordinary to take your camera to an auto shop or send it back to the maker to have the sensor cleaned, we have a couple of stunts to enable you to do that less every now and again.

To begin with, take some electrical tape, crease it over, and take advantage of within your camera body top so it's clingy on the two sides. This will help by having coasting soil and residue adhere to the tape instead of your sensor while you're putting away your camera. Next, purchase a Giottos Rocket Blaster and make certain to utilize it as often as possible. It's an excessively powerful device for speedy cleanings of residue that isn't as of now completely adhered to your sensor. One final tip: ensure your camera consistently is killed when exchanging focal points. At the point when turned on, camera sensors hold a little static charge, making them magnets for residue. By killing your camera before exchanging focal points, you'll guarantee that your camera isn't accidentally pulling in soil and flotsam and jetsam. With these tips and ordinary utilization of the programmed sensor cleaning highlight that most cameras offer, ideally you won't be clone stepping and spot recuperating for quite a long time in post.

Mirrorless and the Battery Life Battle

At the point when individuals talk about mirrorless cameras, probably the greatest objection you'll find out about is the shorter battery life contrasted with DSLRs. While this is a legitimate contention, don't give it a chance to drive you off from mirrorless and realize that what's to come is brilliant. Cameras like the Sony Alpha a6500, Fujifilm X-T2, and Olympus OM-D E-M10 III do will in general have moderately short battery lives and we would prescribe purchasing a couple of additional batteries for these frameworks on the off chance that you plan on being out throughout the day. In any case, more up to date frameworks like the Sony a7R III and Panasonic Lumix G9 brag greater and more up to date batteries that are considerably more viable than their ancestors. While they may not convey a remarkable same limit as what one may be utilized to with a computerized SLR, these bigger batteries can last through an entire day of shooting and will pack all that could possibly be needed power for generally picture takers. While regardless we prescribe conveying an additional battery or two as a reinforcement (it never harms beside the additional weight), you shouldn't have a similar battery uneasiness as in the beginning of mirrorless.

Notwithstanding what body you're shooting with, there are a couple of things you can do to enable your batteries to last somewhat more. First-and it might appear glaringly evident make certain to kill your camera when you're not shooting. It's truly ordinary to snap a couple photographs and stroll around with the camera still on, and you'll spare significant battery life by making sure to flip the camera off among scenes and shots. Next, put your camera in "off-line mode" except if you are utilizing the Wi-Fi. Most new cameras have Wi-Fi capacities, which is an incredible component, however can be depleting on your batteries through the span of a day. Except if you're effectively utilizing it, flip it off and spare some juice. Last, in chilly situations, make a point to keep your batteries warm. This can appear to be a touch of a burden, however removing a battery from your camera and placing it in a warm pocket when not shooting can mean the distinction between a battery that endures throughout the day and one that passes on way too rapidly.

Focal point Types

Mirrorless cameras are still generally new, with most having been discharged over the most recent five years. In like manner, the focal point choice is less changed than for Nikon and Canon DSLRs, which have been available for a considerable length of time. Olympus and Panasonic mirrorless cameras have Micro Four Thirds mounts and you can utilize these cameras and focal points reciprocally. The choice of Micro Four Thirds focal points is monstrous and ranges from spending plan to proficient. Sony's E-mount focal point contributions have developed altogether, and there are a lot of good choices for their Alpha arrangement cameras (though not exactly Micro Four Thirds). Fujifilm has less XF-mount focal points yet there are a lot of value models, especially at the top of the line. Nikon and Canon have significantly more restricted focal point accumulations, yet as they keep on developing into mirrorless, we hope to see a huge increment in the accessible alternatives generally rapidly.

The Emergence of Nikon and Canon

An unavoidable issue mark in the mirrorless blast has been: the place do Nikon and Canon fit into the majority of this? As two of the greatest players in the photography world and with such huge numbers of followers who have shot with either brand for quite a long time, it was somewhat confounding to see their moderate movement and faltering to bounce on the mirrorless train. That all changed in 2018, when Canon discharged the EOS R and Nikon the Z6 and Z7. Each of the three models are full-outline powerhouses intended to clash with Sony and the underlying outcomes have been amazing. Regardless we like Sony's lineup best, and especially because of its multi-year head start on making local mirrorless focal points, yet you can expect this weapons contest to keep on warming up in 2019 and past.
