The A7R IV’s subtle design tweaks make it handle much better than the A7R III before it, and the resolution puts it well ahead of all its full frame mirrorless rivals for megapixels – and yet it has a great ISO range and 15-stop dynamic range too. Sony’s hybrid AF system just keeps on getting better and better, but 4K video stays capped at 30fps, which is mildly disappointing.
The A7R IV is a unique camera – one that appears to be just as comfortable out in the wild, shooting action and wildlife, as it does in the studio taking 61-megapixel product photos. Is it too much camera for most people? Probably, but if you want billboard-worthy detail, or earn your crust shooting commercial work, it might just be the only camera you need – in or out of the studio. Videographers will want to look elsewhere, but with the best autofocus system around, 10fps burst shooting and improved ergonomics, the A7R IV is a camera with few weaknesses and exciting potential.
