Sony is a leader in mirrorless cameras with its full-frame Alpha series, but as the series has expanded to four models, selecting the most appropriate one can be confusing. In the current lineup, the A9 II, A7 III, A7R IV, and A7S II are all capable models, but each provides unique advantages that may make it better or worse in any given situation.

The most obvious difference in these Sony cameras is the sensor resolution, which varies considerably from the A7R IV’s 61 megapixels down to the A7S II’s 12. The A9 II and A7 III take up the middle spots with 24 megapixels, but the A9 boasts higher performance – and a much higher price. With hands-on experience with nearly every full-frame Sony mirrorless model since the series launched in 2013, we’ve pinpointed the differences to help you figure out which is best for you.

Choosing the best Sony full-frame mirrorless camera used to be pretty straightforward, simply because there weren’t very many available.

For years, only Sony made mainstream full-frame mirrorless cameras. The Alpha A7 was the first, released in 2013. It took half a decade for the competition to begin to catch up, if we discount the various Leica models, which are too pricey for most of us.

But then in 2018, Nikon, Panasonic, and Canon all announced their first mirrorless full-frame cameras, and in 2019 we were holding expanded with new bodies and lenses.

Right now, we think the Sony a7R IV may be the best full-frame mirrorless camera you can buy. It’s small, light and relatively affordable while offering excellent performance and handling. But it’s a close call between that camera and the Sony A7R III, which is a good all-rounder at a sensible price.

Some consider the full-frame sensor to be the perfect sensor size and when it’s combined with a mirrorless camera, you get smaller camera bodies, without any reduction in image quality, all without the size of a large full-frame DSLR. Ideal for the professional and advanced photographer, looking to find the best image quality possible, along with better low-light results.

Sounds good, best? Well, if you agree, we’ve put together a list of the best full-frame mirrorless cameras currently available so you can make a more informed choice when parting with your hard-earned cash.
