The A5100 is 6 mm narrower, 25 mm shorter, 23 mm slimmer and 104 g lighter than the EOS M50.
Drawn to scale from the makers' dimensions (W × H × D). Front shown, depth on the slanted edge.
EOS M50 — Casual & Vlogging: The EOS M50 is the most complete-feeling entry-level EF-M camera — built-in EVF, fully articulating screen, Dual Pixel AF, and a well-designed compact body. Its 4K video carries a significant crop and loses Dual Pixel AF, making 1080p the practical option — but for stills and casual video, it remains an excellent used-market 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.
