Sony a7R IV Review
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.
Landscape photographers, wedding and event shooters, studio photographers that specialize in portraits and product photography, and anyone that wants to make really big prints.
Dedicated sports and action shooters, those that must frequently switch from shooting stills to video and back again.
