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.

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.

Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
