Verdictwhich should you buy?
DC-G100D — Vlogging, Content Creation & Lightweight Travel: The lightest capable MFT mirrorless for vloggers — phase-detect AF, directional audio, and the full Lumix lens ecosystem under 350g.
A5100 — Casual & Travel: 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.
