GearScore™ Verdict — Which should you buy?
Professional Content Creators & Adventure Filmmakers — Hero 13 Black (2024): The most capable GoPro ever — interchangeable lenses and GP-Log open up professional possibilities that no previous action camera could touch.
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.
