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.
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.
