GearScore™ Verdict — Which should you buy?
Professional Video, Filmmaking & Hybrid Shooters On L-Mount — Lumix S5 IIX (2023): The S5 II with ProRes RAW and 6K Open Gate — the most serious L-mount video tool in a portable, weather-sealed body.
Professional Video & Low-Light Filmmaking — A7S III (2020): 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.
