Call it the obvious choice, but theis our pick for the best mirrorless camera. It’s not the cheapest, and its 61-megapixel sensor is overkill for many, but no other camera has done as much to continue pushing the boundaries of digital imaging forward. We were immensely impressed with the A7R IV’s image quality, handling, and autofocus performance, the last of which is simply the best in the business. This is a powerful, professional tool that also happens to be approachable and easy to use.
However, its high price and extreme resolution may keep it limited to a relatively small niche of photographers. It’s also not the best video camera, if that’s important to you (although, it’s certainly not bad). Here are the rest of our favorites mirrorless cameras, from basic beginner models to powerful professional tools.

Why should you buy this: 61 megapixels of full-frame glory
Who’s it for: Professional and enthusiast photographers that like big prints, big details, or big crops
Why we picked the Sony A7R IV:
Remember when 45 megapixels was a big deal? The Sony A7R IV packs in 61, offering more resolution than an 8K TV. That’s enough to make very detailed 30-inch prints, or crop a photo significantly and still get a sharp result. But while many high-resolution cameras will slow you down, the A7R IV can fire away at a 10 frames per second. That won’t win a race with the sports-oriented A9, but it’s plenty of speed for most users.
If somehow 61 megapixels isn’t enough, a pixel shift mode can be used to create a 240-megapixel image, although you’ll to stitch it together later using Sony’s proprietary software. Equally impressive are the 15 stops of dynamic range that will help keep more details intact in high contrast scenes.
Sony A7R IV also packs in the same old features that have kept the entire A7 series at the top of our lists for years. Five-axis stabilization is built into the body, the autofocus system is the best in the business thanks Real-Time Tracking and Real-Time Eye AF, and it can shoot decent, if not class-leading, 4K video.
Those features are wrapped up in a body that’s familiar to anyone who’s handled a Sony mirrorless camera before, but Sony has made some small enhancements. The grip is a bit deeper on the A7R IV and the weather sealing has been improved. The body houses a 670-shot battery which is leagues ahead of the mirrorless competition at this point.
You’ll need perfect focus and technique to actually take advantage of all those megapixels, but the A7R IV makes this as easy as possible. No, it’s not cheap, but for the most demanding photographers, the Sony A7R IV is worth it.
Runner-up: Panasonic Lumix S1R
Before the A7R IV, it was the Lumix S1R that held the title of best mirrorless camera, and it still holds some advantages. While large, professionals will appreciate all of the direct-access control and top LCD panel. While its 47MP sensor is down on resolution compared to the Sony, that’s still quite a lot of pixels — plus, the S1R’s high-resolution mode can output a merged, 188MP RAW or JPEG straight from the camera that you can take into any standard image editing app. It doesn’t have the Sony’s speed or autofocus prowess, but it’s still a worthy machine.

Why you should buy this: Impressive image quality, robust design, pro video features
Who’s it for: Serious photographers who need a rugged, capable camera
Why we choose the Panasonic Lumix S1:
The Panasonic Lumix S1 isn’t exactly what we expected from a mirrorless camera — but in many ways, it exceeded those expectations. Besides the excellent image quality coming from the full-frame 24-megapixel sensor, a 96-megapixel high-resolution mode lets you capture even more detail when using a tripod (and doesn’t require proprietary processing software like the Sony A7R IV’s high-resolution mode). We were very impressed with the out-of-camera JPEG image quality, which produces excellent color and contrast, while the RAW images offer plenty of flexibility and strong high-ISO performance.
The S1 uses contrast detection autofocus instead of the usually faster phase detection, but Panasonic narrowed the gap thanks to its proprietary Depth From Defocus technology. Autofocus tracking and subject recognition are good — if not quite to the level of Sony’s more advanced Real-Time Tracking — and while speed is often indistinguishable from competing phase-detection systems, we did notice some occasional misses that cropped up seemingly at random.
The control scheme doesn’t skimp on anything and is highly customizable, offering more direct-access control than mirrorless cameras from other brands. It also offers both SD and XQD card slots, with support for even faster CFExpress cards coming in the future. The body is fully weather-sealed and houses the same electronic viewfinder as the A7R IV, with 5.7 million pixels and a refresh rate of 120 frames per second.
On the video front, the S1 was the first full-frame camera to record 4K video at up to 60 frames per second (alongside its sibling, the Lumix S1R). But that’s not all. A paid firmware upgrade takes the camera to the next level, unlocking full V-log recording and 10-bit 4:2:2 color. The camera can also output a clean video signal over HDMI for even higher-quality recording with an external video recorder. For the aspiring filmmaker, the S1 has a big edge over the competition.
On the downside, all of this makes the camera quite heavy. At about 2.25 pounds, it weighs more than some full-frame DSLRs. The Lumix S1 may not be the best camera for travel photography because of that, but it is otherwise a tremendous achievement that leaves very little to be desired.
Runner-up: Sigma Fp
The Sigma Fp is one of the most unique cameras we’ve ever tested. The Fp is minuscule — it’s the smallest full-frame mirrorless camera — but boasts some incredible video features, including internal RAW recording. However, to get the most out of it, you need a number of accessories, including an external USB drive. The S1 is simply a more complete camera out of the box, making it easier to get up and running. High-end productions may find something like the Sigma Fp is the tool they need, however.

Who’s it for: Pros and enthusiasts who want both portability and strong performance in tough lighting conditions
Why we picked the Sony A7 III:
The Sony A7 series has long given us some of our favorite digital cameras — and the A7 III brings some of the best qualities of the series together in one camera. With the low light performance of the A7S II, the dynamic range of the A7R III, and some of the A9’s blazing speed, the A7 III is plenty of camera for many photographers — and yet it’s the least expensive current full-frame model in the series.
The A7 III sports a backside-illuminated (BSI) 24-megapixel sensor that delivers impressive image quality, with great results even at very high ISOs in low light scenes. Equally impressive is the dynamic range, which helps keep more of the details in the shadows and highlights intact. The five-axis stabilization system doesn’t hurt, either, and further improves low light performance by letting you shoot at slower shutter speeds. The camera also offers a solid 4K video mode, with a plethora of customizable options for adjusting the look of the picture, although it lacks the 10-bit output of the Nikon Z 6.
Sony has had time to fine-tune the A7, and the third generation is a refined, high-end product. Autofocus is quick to lock on even when lighting is limited and the 10-fps burst rate holds for 40 RAW files. Perhaps most impressive is how much Sony has improved the battery, which can power the camera for over 700 exposures, the best we’ve seen in mirrorless.
The control scheme and menu system aren’t our favorites, and the 2.3-million-dot electronic viewfinder falls behind competing models, but the A7 III offers plenty of features and unbeatable low light performance for the price.

Why should you buy this: Excellent images and solid performance for less money than a flagship phone
Who’s it for: Photographers who want great pictures in a portable form factor at a good price
Why we picked the Fujifilm X-T30:
Full-frame cameras may be all the rage these days, but Fujifilm continues to prove there’s plenty of value in the smaller APS-C format. The Fujifilm X-T30 isn’t the cheapest camera you can buy, but it may just be the most valuable. It takes the best features from the impressive X-T3 and whittles away a few of the less essential options to make an affordable, but still very capable, camera. What you get is a camera with a less robust body and a few high-end features, but one that produces image quality that’s just as impressive as the camera that costs almost twice as much.
The X-T30 uses a 26-megapixel X-Trans sensor that’s capable of capturing some excellent images as well as 10-bit 4K video. A 425-point phase-detection autofocus system is fast, accurate, and fills the entire frame. The X-T30 can’t keep up with the X-T3’s burst rate and larger image buffer, but its 8 frames per second are still plenty for most photographers.
The camera can also handle 4K video quite well, offering both Fujifilm’s F-Log profile and 10-bit 4:2:2 output making it suitable for even some professional video applications. It’s one of the best video modes we’ve seen in a camera that doesn’t breach the four-figure price barrier.
Fujifilm wraps all of that tech into a body that’s a mix of retro and modern, with both physical dials and a touchscreen. Compared to the X-T3, the biggest things missing are the second SD card slot and weather-sealing, but the X-T30 is a stellar shooter for the price.
Runner up: Sony A6100
We love the Fuji for its styling and lens collection, but there’s no doubt that the new Sony A6100 has some performance advantages. The big one is autofocus, as the A6100 inherits the same Real-Time AF features as more-expensive Sonys, making it easy to track subjects and ensure every shot is tack-sharp.

Why should you buy this: The GH5 is a hybrid camera that’s can shoot both stills and video without cutting corners.
Who’s it for: Creatives who put as much emphasis on motion content as they do on still photos.
Why we picked the Panasonic Lumix GH5:
All the cameras on this list shoot video and most even shoot 4K. But in most cameras, video is a secondary focus. Not so with the Lumix GH5. Where many DSLRs and mirrorless cameras have short recording limits for 4K, the GH5 will happily continue shooting until the card fills up or the battery dies — and it boasts smooth-as-butter 60-fps 4K, to boot. Beyond that, it offers a number of video features targeting professional users, including 10-bit 4:2:2 recording, clean HDMI output, and an optional log-gamma profile via a paid firmware upgrade. (The recently released Lumix GH5S takes video quality to a new level, but the standard model remains the better choice for most users thanks to its 5-axis image stabilization.)
While video is a big selling point for the GH5, the camera can hold its own among other Micro Four Thirds shooters for still photos. The five-axis image stabilization plays a role for both videos and photos, the Depth from Defocus autofocus is nearly as quick as on the Lumix S1 and burst shooting is even faster, up to 9 fps with continuous autofocus or 12 fps with focus locked on the first frame. The GH5 also has several Panasonic-exclusive features, including 4K and 6K photo modes where you can choose the focus point after the shot, merge several images for a deeper depth of field, or shoot reduced-resolution still photos at 60 or 30 fps, respectively.
Like the hybrid photo-video capabilities, the GH5’s body feels more like a DSLR/mirrorless hybrid. It’s smaller than most DSLRs, but there are plenty of physical controls, a great electronic viewfinder, and dual SD card slots. While you can buy cameras with larger sensors for the same price, the GH5 has the best mix of photo and video options we’ve seen yet and outclasses many cameras costing much more when it comes to pro video features.

Why you should buy this: Compact, beginner-friendly design meets fast performance
Who’s it for: Beginners and anyone who wants better photos than a smartphone without the bulk (or work)
Why we picked the Olympus PEN E-PL9:
Sure, full-frame mirrorless cameras offer superior image quality, but the larger sensors can get in the way of what the mirrorless camera was originally designed for in the first place — compact size. The Olympus PEN E-PL9, built on the same Micro Four Thirds format as the Panasonic Lumix GH5, is easy to bring along anywhere thanks to the ability to fit in a small bag, purse, or even a jacket pocket. The camera is also beginner-friendly and easy to use for those simply looking for better quality without diving into the realm of manual controls (though those manual controls are certainly there for those who want them).
The 3-axis image stabilization, while not Olympus’ best, is still very helpful for handheld shots. In practice, we occasionally shot shutter speeds as slow as 1/2 second and still got sharp results. Olympus also did well with the HDR and panorama modes, both useful features for outdoor landscape photography when you don’t want to fuss with manual settings.
When it comes to getting an affordable travel camera, the E-PL9 is an excellent option, even if it doesn’t technically live up to the image quality of larger-sensor competitors. It’s the ideal camera for anyone looking to step up from smartphone photography without getting anything too heavy.

What is a mirrorless camera?
A mirrorless camera is a type of camera that uses interchangeable lenses. It’s related to the digital single-lens reflex (DSLR) camera, but do not confuse the two as the same. A DSLR uses a mirror to reflect light from the lens to an optical viewfinder (OVF). When the shutter button is pressed, a mirror flips up to allow light to hit the sensor.
Mirrorless cameras do away with the mirror system (hence the name) and instead use electronic viewfinders, or simply no viewfinder at all (as is the case with the E-PL9). This allows for lighter and smaller designs, but professional models can still be somewhat bulky and heavy. Like DSLRs, mirrorless cameras let you attach a variety of lenses and typically use larger sensors than point-and-shoot, which leads to superior image quality.
Are mirrorless cameras better for video?
While there’s no technical reason why a DSLR couldn’t be built with the same video specifications as a mirrorless camera, the latter tends to have some inherent advantages. A mirrorless camera’s electronic viewfinder, for example, can be very useful when shooting video in bright light, whereas the optical viewfinder of a DSLR simply cannot be used in video mode. Due to their nature as live-view-only cameras, mirrorless cameras also often feature better autofocus systems than a DSLR in live-view mode. Canon offers one exception to this, with its fast Dual Pixel Autofocus that is found on both its mirrorless and DSLR models. Some of the best video cameras on the market, like the Panasonic GH5, are mirrorless cameras — but this has as much to do with the brand’s experience making video cameras as it does with the format itself.
Can a DSLR lens be used with a mirrorless camera?
Oftentimes, yes, but it always requires an adapter. Canon EF-mount DSLR lenses can be adapted to Canon RF and EF-M mount mirrorless cameras via a first-party adapter that offers near-identical performance. Likewise, Nikon F-mount DSLR lenses can be attached to Z-mount mirrorless bodies via Nikon’s FTZ adapter. It is also possible to attach Canon and Nikon lenses to the likes of Sony and Micro Four Thirds mirrorless cameras, but this must be done through a third-party adapter and the lenses may not perform as fast as they do on their native systems.
Should I buy a DSLR or a mirrorless camera?
Mirrorless cameras have grown increasingly popular and are our go-to recommendation for most photographers today. The biggest advantage a DSLR still offers is the battery life, which often rates well over 1,000 shots per charge. We’ve found DSLRs also tend to offer more reliable autofocus performance in low light, but mirrorless cameras are getting better here with each new generation. Like it or not, mirrorless is the future, and that’s probably where your investment should be made.
Who makes the best mirrorless camera?
While we put a Panasonic at the top of this list, the truth is that many brands make great mirrorless cameras today. If you’re looking to buy your first camera, consider which features are most important to you and look for the brand that does the best job with them. That could be autofocus performance or it could be video quality; you may want more speed or more resolution. Sony has the most experience with full-frame mirrorless, but we’ve been very impressed with how quickly Nikon and Panasonic have caught up to, and even surpassed, Sony in some ways. Olympus has the best image stabilization in the OM-D E-M1 X, a camera that didn’t find a place on this list, but is still very good.
