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 & High-Resolution Studio Work — A1 II (2025): The most complete camera ever made — 50MP, 30fps, 8K, and the world's best EVF in a single flagship body.
