EOS R10vs A7S IIIvs Sony FX30
Which should you buy?
Beginners & Vlogging — EOS R10 (2022): Canon's most affordable RF body — Dual Pixel AF and a vari-angle screen in a compact, lightweight package.
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.
Video Creators & Filmmakers — Sony FX30 (2022): The Cinema Line entry point — S-Cinetone colour science, 4K/120p, and XLR audio in a compact, affordable body that punches far above its price.
