EOS M10vs A7 III
GearScore™ Verdict — Which should you buy?
Casual & Everyday — EOS M10 (2015): The EOS M10 is Canon's most basic EF-M mirrorless — small, stylish, and approachable, with 18MP and a tilting touchscreen. It lacks the specs of newer EF-M bodies but delivers solid results for everyday shooting and represents an affordable entry into the Canon mirrorless ecosystem.
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.
