GearScore™ Verdict — Which should you buy?
Video, Independent Filmmaking & Documentary — GH4 (2014): The world's first consumer 4K camera — the GH4 changed independent filmmaking and proved that broadcast-quality video didn't require a cinema camera budget.
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.
