GearScore™ Verdict — Which should you buy?
Enthusiast Photography, Travel & Street — X-T30 III (2025): 40MP resolution and flagship-level subject detection in the most affordable X-T body — the best value Fujifilm camera ever made.
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.
