Which should you buy?
Commercial, Studio & Landscape Professionals — Fujifilm GFX 100S II (2024): 102MP medium-format quality in the most accessible GFX body — the best entry point to the Fujifilm GFX system.
Outdoor & Adventure — OM-5 (2022): The toughest camera at this price — IP53 weather sealing and 7.5-stop IBIS built for adventure photographers.
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.
