EOS M50 IIvs Lumix S5 IIvs A7S III
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.
Hybrid Video & Photography — Lumix S5 II (2023): Phase-detect AF changed everything for Lumix — the S5 II delivers exceptional hybrid performance with 6K video and genuine full-frame value.
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.
