GFX 50S IIvs X-E4vs 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.
Compact Street & Travel Photography — X-E4 (2021): The X-E4 is for photographers who want the minimum camera that still delivers maximum image quality. If you love shooting from the rear screen and want the smallest possible X-mount body, this is your camera. If you need a viewfinder or IBIS, look at the X-S20 or X-T30 II.
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.
