Verdictwhich should you buy?
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.
A7R V — Landscape, Studio & Commercial: 61 megapixels and 8-stop IBIS in a weather-sealed body — the reference resolution camera for commercial and landscape professionals.
