What we like:

  • Expansive resolution
  • In-body image stabilization
  • 4K/30p video capture
  • Robust contruction

What we don't:

  • Video limited to 8-bit capture
  • High-res files must be assembled on PC
  • Complex interface, clunky touchscreen
The Sony a7R IV is a 60MP full-frame camera capable of 4K video and high-speed capture. It features an AF tracking system that's both simple and powerful, as well as revised ergonomics.
The a7R IV has a deep hand grip and large buttons which are easily operated with gloves. The viewfinder is high resolution, but doesn't use its full resolution at default settings. The touchscreen is somewhat under-used and the menus are a little overwhelming. Dual UHS-II card slots will be helpful for those shooting fast action bursts of images. Overall, it's a comfortable and responsive camera.
The a7R IV is among the most capable cameras we've tested
The a7R IV's autofocus tracking offers an industry-leading combination of power and simplicity. It tracks subjects around the frame and will choose eye, face or subject AF as appropriate. Accuracy drops slightly while shooting 8 and 10fps bursts, when shooting backlit subjects and in very low light, but overall the a7R IV's speed and AF system adds significant flexibility for a high-res camera.
Image quality is very impressive. There's a very slight noise increase over its predecessor but the detail levels are extremely high and the dynamic range is very good. JPEG color is attractive, too. A multi-shot 240MP mode is included but can only really be used for static subjects.
The a7R IV's 4K video is the most detailed among all its high-resolution mirrorless camera peers. You can capture footage from the full sensor width but, or get more detailed results from a 1.6 or 1.8x crop region. All output is 8-bit, which limits processing flexibility, compared with most contemporary rivals. It also accepts digital audio input, either from a dedicated mic or the optional XLR adapter.
The Sony a7R IV is among the most capable cameras we've tested, ever. From the impressive resolution to the easy-to-use autofocus system and fast burst speeds to good video quality, there is little you can't photograph and produce a billboard-sized print of if you have an a7R IV in your hands.
