dpreview has just completed the full review of recently released Sony a7R IV (B&H Photo Video/Adorama/Amazon) full frame mirrorless camera today. It received their gold award and 91% overall score. Currently the best camera reviewed by dpreview.
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.
