GFX 50S IIvs X-A7vs Z6 II
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.
Beginner Fujifilm — X-A7 (2019): The most affordable X-mount entry — Fujifilm colour and film simulations with a large flip screen for beginners.
All-Round Full-Frame Photography — Z6 II (2020): The Z6 II is the Nikon most photographers should buy. It's balanced across every discipline — stills, video, autofocus, weather sealing — without overpaying for megapixels you don't need. The Z-mount glass is superb.
