GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Press Photography — EOS-1D X Mark III (2020): Canon's DSLR masterpiece — 20fps live view, 5.5K RAW, 191 cross-type AF points, and dual CFexpress. Almost certainly the finest optical viewfinder camera ever made.
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.
Full-Frame Entry — EOS R8 (2023): Canon's most affordable full-frame mirrorless — 4K/60p 10-bit and class-leading Dual Pixel AF at an accessible entry price.
