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.

Street Portraits & Reportage — Ricoh GR IIIx (2021): APS-C in a shirt pocket with a 40mm perspective — the GR IIIx is the ideal street portrait compact for photographers who want a slightly tighter frame.

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.
