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.
Travel, Street & Premium Compact Shooters — Leica Q3 (2023): 60MP, Summilux 28mm, IBIS, and weather sealing — the Q3 is the ultimate fixed-lens camera for those who can justify the cost.
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.
