EOS M50 IIvs A7 IIIvs Sony FX30
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.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
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.
