Which should you buy?

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.

Portraits & Action — EOS R6 Mark II (2022): 40fps burst, 8-stop IBIS, and Canon's best-in-class Dual Pixel AF — exceptional for action, sports, and portrait work.

All-Round Full-Frame Photography — Z6 II (2020): The Z6 II is the Nikon most photographers should buy. It's balanced across every discipline — stills, video, autofocus, weather sealing — without overpaying for megapixels you don't need. The Z-mount glass is superb.
