KFvs A7R IV
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.
Landscape, Studio, Commercial — A7R IV (2019): 61MP in a mirrorless body — the resolution benchmark.
