VS
GearScore™ Verdict — Which should you buy?
Wedding, Portrait, Sports, Video — EOS R6 (2020): The camera that made Canon's RF system worth taking seriously.
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.
