GearScore™ Verdict — Which should you buy?
Casual & Everyday — EOS M100 (2017): The EOS M100 is Canon's most stripped-back EF-M camera — small, simple, and focused on making great photos easy. Dual Pixel AF, 24MP, and a tilting touchscreen are its strengths; no EVF, no IBIS, and no 4K are its compromises. A solid, affordable first mirrorless for casual photographers who want more than a smartphone.
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.
