GearScore™ Verdict — Which should you buy?
Hybrid Photography, Travel & Video On Sony Aps-C — A6600 (2019): The APS-C Sony that has everything — IBIS, real-time Eye AF, excellent battery life, and 4K/30p in a 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.
