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.
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.
Professional Video, Documentary & Hybrid Commercial Work — EOS R5 C (2022): Canon's R5 reborn for cinema — 8K RAW unlimited, Cinema EOS colour science, and 45MP stills in a weather-sealed body.
