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.

Casual & Travel — A5100 (2014): The A5100 is one of the smallest APS-C mirrorless cameras ever made. Its 24MP sensor, phase-detect AF, and selfie-friendly flip screen pack remarkable capability into a shirt-pocket-sized body. No EVF or hot shoe limits it for serious use, but as a compact travel camera or beginner's first mirrorless, it punches well above its price on the used market.
