GearScore™ Verdict — Which should you buy?
Street, Travel & Everyday Photography — X100F (2017): The X100F is the camera that made the X100 series legendary — 24MP X-Trans III, a hybrid viewfinder, and the best fixed 35mm compact lens available.
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.
Who should buy what
X100F (2017)
