The A5100 is 34 mm narrower, 40 mm shorter, 13 mm slimmer and 427 g lighter than the Zf.
Drawn to scale from the makers' dimensions (W × H × D). Front shown, depth on the slanted edge.
Zf — Street & Travel Photography: Full-frame performance in a stunning retro body — the Zf's 8-stop IBIS and gorgeous design make it uniquely compelling.
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.
