GearScore™ Verdict — Which should you buy?
Video & Documentary — GH7 (2024): The GH7 is the GH series at its peak — phase-detect AF finally arrived, alongside 5.7K/60p open-gate, C4K/60p 10-bit 4:2:2, and ProRes RAW. A landmark video camera in the Micro Four Thirds format, and the most complete GH Panasonic has ever built.
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.
