Verdictwhich should you buy?
KF — Landscape & Outdoor: 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.
