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.
Sports & Photojournalism Professionals — Canon EOS R3 (2021): The pinnacle of Canon's mirrorless lineup for speed — Eye Control AF and 30fps burst in the most rugged body Canon has ever produced.
Vlogging & Travel — PowerShot V1 (2025): The PowerShot V1 is Canon's best compact camera — a 1-inch stacked sensor, Dual Pixel CMOS AF, 4K/60p, built-in ND, and an articulating screen in a pocketable body. It is the compact camera Canon's content-creator audience has been waiting for, and a genuine step forward over the G7X series.
