Sony Alpha a7R IV Black Review

The Sony a7R IV is a resolution specialist for pixel-peepers. If you don't print billboards or crop like a madman, a cheaper camera will serve you better.

The Sony a7R IV is a pixel monster that makes you question why you'd ever need a medium format camera. That 61MP sensor is the main event here, delivering detail so sharp it feels like cheating. But here's the thing to know: this camera is built for photographers who chase resolution above all else, and it makes some serious trade-offs to get there.

The 61MP sensor is genuinely impressive, landing in the 80th percentile for sensor performance in our database. It's the kind of resolution that lets you crop aggressively and still have a usable file. But the autofocus performance, sitting at the 44th percentile, was a surprise. For a camera at this price, we expected it to be a bit snappier, especially for fast-moving subjects. The 10fps burst is solid, but it's not the speed demon some competitors are.

At $3,298, it's a lot of money. You're paying almost exclusively for that sensor. If you don't need 61MP for commercial work, large prints, or extreme cropping, you're overpaying for power you won't use.

The Sony a7 IV is the obvious sibling to consider. It gives up a ton of resolution (33MP vs 61MP) but gains much better autofocus, better video features, and a more balanced overall package for about a thousand dollars less. If you need speed and reliability over pure resolution, the Canon EOS R6 Mark II is a beast for action and has far superior battery life. The a7R IV wins on paper with pixels, but loses in real-world usability for anything that moves quickly.

If you shoot sports, wildlife, or weddings where catching the moment is everything, this isn't it. The autofocus isn't bad, but it's not the best. Go get a Canon R6 Mark II or a Sony a9 instead. Also, if you hate giant files clogging up your hard drives, look elsewhere.

We recommend the Sony a7R IV only for a specific type of photographer: the landscape shooter, the studio commercial photographer, or the archivist who needs every pixel they can get. For everyone else—wedding photographers, sports shooters, travel bloggers—the compromises in autofocus and handling aren't worth the resolution bragging rights. Get the a7 IV instead and spend the leftover cash on glass.
