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.
Portrait, Landscape & Studio Photography — A7R II (2015): The A7R II transformed the A7R series — adding IBIS, 4K video, BSI sensor tech, and phase-detect AF in one generation. A landmark Sony camera.
