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.
Professional Sports, Wildlife & High-Resolution Studio Work — A1 II (2025): The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
