GearScore™ Verdict — Which should you buy?
Travel, Street, Wildlife & 4k Video — A6300 (2016): The camera that proved Sony APS-C was serious — world's fastest AF at launch, uncropped 4K, and 11fps in a compact 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.
