A5100vs A7C II
GearScore™ Verdict — Which should you buy?
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.
Full-Frame Hybrid — A7C II (2023): Full-frame AI autofocus in the most compact body available — the best camera under £1,500 for hybrid shooters.
