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.
Portrait & Street — EOS M6 Mark II (2019): The M6 Mark II is the peak of the EF-M system — 32.5MP, 14fps, and Dual Pixel CMOS AF II in a compact rangefinder-style body. No built-in EVF is the main compromise, but the optional EVF-DC2 resolves this. An outstanding used-market buy for photographers who want high resolution and fast AF in a genuinely compact body.
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.
