GFX 50S IIvs Fujifilm X100VIvs A6400
Which should you buy?
Studio & Portrait Specialists — GFX 50S II (2021): Medium format quality at the most accessible price ever — 51MP detail and tonal richness no APS-C or full-frame body can replicate.
Street, Travel & Everyday — Fujifilm X100VI (2024): The best fixed-lens camera ever made — 40MP, 7-stop IBIS, film simulations, and a design icon. Wildly oversubscribed for good reason.
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.
