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 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.
First Camera / Beginner Photography — EOS R100 (2023): The R100 does the basics well at the lowest possible price point. Its main value is as a gateway into the Canon RF ecosystem — the lenses you buy now will work on any Canon body you upgrade to later. Modest ambitions, reliably met.
