EOS R50vs EOS R8vs A7 III
Which should you buy?
Beginners & Family — EOS R50 (2023): Canon's most beginner-friendly RF body — Dual Pixel AF and beautiful colour science in an approachable package.
Full-Frame Entry — EOS R8 (2023): Canon's most affordable full-frame mirrorless — 4K/60p 10-bit and class-leading Dual Pixel AF at an accessible entry price.
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.
