GearScore™ Verdict — Which should you buy?

Wildlife, Sports & Action — EOS R7 (2022): The EOS R7 is one of the most complete APS-C cameras ever made. It combines a class-leading resolution sensor with best-in-class IBIS, 4K/60p video, weather sealing and 15fps burst. For wildlife, sports and action photographers on an APS-C budget, nothing else comes close.

Landscape, Studio & Commercial Photography — A7R III (2017): The camera that converted professionals to mirrorless — 42MP, IBIS, and 10fps in a body that still competes today.
