Verdictwhich should you buy?
A7S II — Low-Light Video, Documentary & Available-Light Filmmaking: A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
FX30 — Video Creators & Filmmakers: 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.
