GearScore™ Verdict — Which should you buy?
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.
Professional Sports, Wildlife & Photojournalism — A9 II (2019): The A9 II polished the A9's groundbreaking formula — 20fps blackout-free, improved subject tracking, and a LAN port made it the professional sports standard.
