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.
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.
All-Round & Video — A6700 (2023): Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
