Verdictwhich should you buy?
A7S III — Professional Video & Low-Light Filmmaking: If video is your primary discipline, the A7S III is the camera. 4K/120p at 10-bit in a weather-sealed body with a 9.44M dot EVF is an extraordinary package. The 12MP sensor isn't limiting for video — and it's usable at ISO 409,600 in a pinch.
ZV-E1 — Video Creators, Vloggers & Filmmakers: Full-frame video quality in a vlogging body — exceptional low-light performance and a genuinely compact form factor.
