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 & Everyday — EOS M10 (2015): The EOS M10 is Canon's most basic EF-M mirrorless — small, stylish, and approachable, with 18MP and a tilting touchscreen. It lacks the specs of newer EF-M bodies but delivers solid results for everyday shooting and represents an affordable entry into the Canon mirrorless ecosystem.
Professional Sports, Wildlife & Photojournalism — EOS R1 (2024): Canon's ultimate professional camera — 40fps, a class-leading EVF, and AI AF that simply doesn't miss.
