GearScore™ Verdict — Which should you buy?
Commercial, Portrait & Landscape Photographers — GFX 100S (2021): 102MP medium-format with IBIS and phase-detect AF at a price that made serious large-format imaging available to a new generation of 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.
