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.

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.

Professional Hybrid Shooters, Portrait & Wildlife — EOS R5 (2020): A landmark camera — 8K video and 45MP in one body set the standard for what mirrorless could be.
