GearScore™ Verdict — Which should you buy?
Canon Mirrorless History & Ef-M Collectors — EOS M (2012): Canon's first mirrorless — a historic body that broke new ground with touch-AF and EF-M, but its sluggish contrast-detect system quickly became its Achilles heel.
Content Creation & Vlogging — A6400 (2019): The best value APS-C Sony you can buy — especially used. Real-time Eye AF at this price point was transformative when it launched and still makes it one of the most reliable autofocus systems in the lineup.
Who should buy what
EOS M (2012)
