GearScore™ Verdict — Which should you buy?
Canon Mirrorless History & Ef-M Collectors — EOS M (2012): Canon's first mirrorless — a historic body that broke new ground with touch-AF and EF-M, but its sluggish contrast-detect system quickly became its Achilles heel.
Casual & Everyday — EOS M10 (2015): The EOS M10 is Canon's most basic EF-M mirrorless — small, stylish, and approachable, with 18MP and a tilting touchscreen. It lacks the specs of newer EF-M bodies but delivers solid results for everyday shooting and represents an affordable entry into the Canon mirrorless ecosystem.
Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.
