GearScore™ Verdict — Which should you buy?
High-Resolution Landscape, Commercial & Studio Photography — Lumix S1R (2019): A 47MP full-frame resolution powerhouse with one of the finest EVFs ever made — the S1R rewards careful, deliberate photography.
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.
