Verdictwhich should you buy?
PowerShot G7X Mark III — Vlogging, Content Creation & Travel Video: The finest vlogging compact available — pocket-sized 4K, a flip screen, mic input, and USB live streaming in one remarkably capable package.
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.
