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.
Travel & Everyday — OM-D E-M10 IV (2020): Compact Micro Four Thirds body with built-in IBIS — ideal for travellers who want stability without bulk.
