GearScore™ Verdict — 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.

Landscape & Outdoor — KF (2022): The Pentax KF is a rare thing — a weather-sealed DSLR with in-body stabilisation and an articulating screen at an accessible price. Video is modest at 1080p/60p, but for outdoor and landscape photographers who prefer optical viewfinders and want real weather sealing, the KF delivers in a format that is increasingly hard to find.
