GearScore™ Verdict — Which should you buy?
Landscape, Travel & Street Photography At Medium Format Quality — GFX 100RF (2025): The world's first medium format compact — 102MP, 28mm, and all 20 Fujifilm film simulations in a fixed-lens body.
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.
