EOS M50 IIvs Z6 IIIvs A6400
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 & Action — Z6 III (2024): Partial-stacked FF sensor for near-zero blackout, 6K RAW video, and 60fps burst — Nikon's most capable hybrid.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
