Sony Alpha a7R IV Black 2019
The 61MP back-illuminated full-frame sensor captures medium-format-level detail with a 15-stop dynamic range, while 10fps continuous shooting handles fast action. A 5.8M-dot electronic viewfinder and 5.5-stop in-body stabilization provide precise framing and sharp handheld shots. This camera is best for studio, landscape, and portrait photographers who demand maximum resolution without the bulk of medium-format systems.
