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.
High-Resolution Creative & Documentary Shooters — Sigma fp L (2021): 61MP and phase-detect AF in the world's smallest full-frame body — the fp L is the most capable iteration of Sigma's extraordinary compact.
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.
