GFX 50S IIvs A7Cvs Sony FX30
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 Travel & Content Creation — A7C (2020): The A7C proves full-frame doesn't have to be bulky. Excellent battery life, reliable Eye AF and a vari-angle screen in a pocketable body is a compelling combination for travel and content creators. The A7C II improved on it, but the original remains a strong value buy.
Video Creators & Filmmakers — Sony FX30 (2022): The Cinema Line entry point — S-Cinetone colour science, 4K/120p, and XLR audio in a compact, affordable body that punches far above its price.
