Canon EOS R3 Initial Review
All product photography by DPReview
The Canon EOS R3 is the company's first high-end mirrorless camera designed for sports, wildlife and photojournalism. It's a full-frame 24MP camera built around the 'RF' lens mount, and in many respects, it appears to be a flagship camera other than the lack of '1' in its name.
The EOS R3 is built around a Stacked CMOS sensor, which delivers fast readout for rapid shooting, responsive autofocus and low rolling-shutter video, but it also includes a host of innovative features, including the return of Canon's Eye Control autofocus system, last seen in film SLRs of the late 90s and early 2000s.
