EOS M50 IIvs A7S IIIvs ZV-E10
Which should you buy?
Beginners & Vlogging — EOS M50 II (2020): Canon's most approachable mirrorless — Dual Pixel AF and beautiful colour science in a beginner-friendly 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.
Vlogging & Video — ZV-E10 (2021): Purpose-built for video creators — real-time Eye AF, flip screen, and excellent 4K at a wallet-friendly price.
