GearScore™ Verdict — Which should you buy?
Travel & Portrait — EOS M5 (2016): The EOS M5 was the first EF-M camera with a built-in EVF — and it made the system feel complete. Fast Dual Pixel AF, a 9fps burst, and a high-resolution articulating screen deliver a confident shooting experience. No IBIS and 1080p video only limit its appeal for hybrid work, but for stills photographers it remains one of the most well-rounded EF-M bodies available.
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.
