EOS R50vs GFX 50S IIvs 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.
Studio & Portrait Specialists — GFX 50S II (2021): Medium format quality at the most accessible price ever — 51MP detail and tonal richness no APS-C or full-frame body can replicate.
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.
