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, Documentary & Rangefinder Enthusiasts — Fujifilm X-Pro3 (2019): The most opinionated camera Fujifilm makes — a hidden screen and hybrid OVF enforce deliberate photography, rewarding photographers who slow down.
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.
