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.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
