OM-D E-M10 IVvs A5100
GearScore™ Verdict — Which should you buy?
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.
Casual & Travel — A5100 (2014): The A5100 is one of the smallest APS-C mirrorless cameras ever made. Its 24MP sensor, phase-detect AF, and selfie-friendly flip screen pack remarkable capability into a shirt-pocket-sized body. No EVF or hot shoe limits it for serious use, but as a compact travel camera or beginner's first mirrorless, it punches well above its price on the used market.
