While you can get great results using a crop sensor camera, a camera with a full-frame sensor will make it easier to work in low light, get a shallower depth of field, and generally capture cleaner, higher-quality images. Though you don't necessarily need a full-frame camera unless you're a pro, those advantages make them well worth considering for hobbyists and enthusiasts. Keep in mind that full-frame cameras generally aren't as portable as their crop-sensor counterparts and tend to come at a premium when it comes to price—lenses will be bigger and pricier, too. However, the barrier to entry is getting lower, with more and more models to suit different needs and budgets.
Thankfully, we've done some of the work in narrowing down those options for you. We've bought and tested over 75 cameras, and below you'll find our recommendations for the best full-frame mirrorless cameras to buy. If you're looking for a camera specifically for low-light shooting, you can also take a look at our recommendations for the best cameras for low light. If you're interested primarily in photography, you can check out our list of best cameras for photography or even more specific picks for landscape photography or wildlife, depending on your needs.
The Sony α7 IV is the successor to the ultra-popular Sony α7 III, taking everything great about it and improving it. It has a more solid-feeling construction, an improved autofocus system, added CFexpress card slot, and more advanced video features for hybrid shooters. While it has a hefty price tag, the α7 IV is the camera to get if you need a full-frame camera that can pretty much do it all.
On top of all the quality-of-life improvements, it has a new 33-megapixel sensor that gives you a ton of leeway for cropping and editing. Unlimited recording times and internal 10-bit 4:2:2 recording also make this a fantastic option for shooting films and other video work. Overall, its flaws are few and far between, the biggest being slower-than-typical burst shooting at this price point with a max of 6 fps when shooting uncompressed RAW files. If you plan on shooting sports and fast subjects, you might prefer the Canon EOS R6 with its 12 fps mechanical burst rate and better ergonomics. Overall, the Sony camera's well-rounded feature set and extensive third-party lens options make it one of the best full-frame mirrorless cameras for enthusiasts.
If cameras like the Sony α7 IV or the Canon EOS R6 are a little out of your price range, the Nikon Z 6II comes in at a slightly lower price point and still has a lot to offer. While its autofocusing doesn't quite reach the same heights as the Sony or Canon, it's still highly effective and will serve you well in all but the most extreme shooting situations. The camera is right up there in build quality, ergonomics, burst rate, and image quality.
The only real downside of the Z 6II is its video capabilities, as it's limited to an 8-bit internal recording, while those pricier competitors can record higher-quality 10-bit video. Nikon's Z-mount lens options are also more limited and generally more expensive—though high-end S-Line lenses are arguably worth the premium. Ultimately, it's an excellent and reliable photography camera that handles remarkably well, thanks to intuitive controls and ergonomics.
If you're on a tighter budget, the entry-level Nikon Z 5 is a fantastic deal. It's similar to the Nikon Z 6II, sitting just below it in Nikon's mirrorless lineup. The cameras look and feel similar, with weather-sealed bodies, excellent ergonomics, high-res viewfinders, tilting screens, and in-body image stabilization. One of the few drawbacks it does have is slow burst shooting—a measly 5 fps vs. 14 fps on the Z 6II. Still, if you don't use continuous shooting much, the Z 5 is an excellent photography camera for its price.
If you're a hybrid shooter or interested in video, be aware that the Z 5 can only shoot 4k footage with a severe crop and offers fewer frame rate options than the Z 6II. The Z 6II also has a slightly more capable autofocus system with more sophisticated tracking. If you can live without adequate 4k recording, though, it performs about on par for image quality and surpasses the more powerful Z 6II for battery life. While some of these things might be dealbreakers, this is still a relatively affordable full-frame camera with a lot to offer for photographers on a tighter budget.
"Cheap" is a relative term here, as the Canon EOS RP will still run you a fair amount of pocket change, but as far as full-frame cameras go, there isn't a more affordable option than this (unless you buy it used, of course). With a decent full-frame sensor packed into a highly portable body, there's a lot to like about this camera, from its impressive autofocus system to its excellent ergonomics and accessible controls. While it's clear Canon skimped on things like build quality and burst rate compared to pricier models, full-frame image quality and lenses have never been more accessible.
Like the Nikon Z 5, it isn't the best option for video shooters, with an even worse 1.74x crop and less impressive video quality. Unlike the Z 5, it doesn't have IBIS. If your main focus is photography, it offers a lot of value, simplicity, and portability, along with a truly great AF system. Overall, it's a solid option for those looking to upgrade from APS-C or jump straight into full-frame photography without breaking the bank.
While full-frame cameras aren't known for their portability, manufacturers have been releasing smaller and smaller models for those who want a more portable kit. The Sony α7C is a great full-frame option for travel thanks to its compact body. It sits somewhere in between the Sony α7 III and the Sony α7 IV in terms of performance, with a better AF system than the α7 III but worse internal video specs than the α7 IV. For image quality, however, it's right up there with both of them.
Of course, some trade-offs come with a more portable camera, most notably the camera's tiny viewfinder and fewer custom buttons. If you're looking for full-frame image quality in a camera that's much easier to take on the go, there aren't any better options than this.
Our recommendations above are what we think are currently the best full-frame mirrorless cameras for most people to buy, according to their needs and budget. We factor in the price, feedback from our visitors, and availability (no cameras that are difficult to find or almost out of stock in the U.S.).
