KFvs A7R
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.
Studio, Tripod Landscape & Camera History — A7R (2013): The world's first 36MP full-frame mirrorless — a landmark camera that launched the A7R series, despite contrast-detect AF and significant shutter shock limitations.
