GearScore™ Verdict — Which should you buy?
Professional Sports, Wildlife & Press Photography — EOS-1D X Mark III (2020): Canon's DSLR masterpiece — 20fps live view, 5.5K RAW, 191 cross-type AF points, and dual CFexpress. Almost certainly the finest optical viewfinder camera ever made.
Casual & Vlogging — EOS M200 (2019): The EOS M200 is Canon's most approachable APS-C mirrorless — slim, light, and simple, with Dual Pixel AF that makes sharp results effortless. No EVF and no IBIS keep it firmly entry-level, but for first-time buyers stepping up from a smartphone, it delivers reliable, confidence-inspiring results in a genuinely compact package.
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.
