The Sony a7R IV is the company's fourth generation, high-resolution full-frame mirrorless camera and is built around a BSI-CMOS sensor that outputs 60.2MP images. Despite its high resolution, it can shoot at up to 10 frames per second with full autofocus and shoot 4K video either from the full width of its sensor or from an APS-C/Super 35 crop. It also gains a 16-shot high-resolution mode that can be used to generate 240MP images of static scenes.
The a7R IV has in-body image stabilization that's usable for still and video shooting. It has a top-notch autofocus system with face and eye detection that sticks to the subject, even if they look away or are momentarily blocked. It has a large, ultra-high-res electronic viewfinder, tilting touchscreen display and dual UHS-II SD card slots. The camera body is sealed against dust and moisture.

The Sony a7R IV is among the most capable cameras we've tested. It makes a compelling case that the days of choosing between speed-oriented cameras and resolution-oriented cameras are coming to an end. It wouldn't be our top choice for sports and action purists (all those megapixels result in many megabytes of storage), but for those users that need this resolution on a regular basis and want to be able to photograph fast-moving subjects when necessary, the Sony a7R IV is the best option on the market right now.
Good for: Landscape photographers, wedding and event shooters, studio photographers that specialize in portraits and product photography, and anyone that wants to make really big prints.
Not so good for: Dedicated sports and action shooters, those that must frequently switch from shooting stills to video and back again.
