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