The A5100 is 26 mm narrower, 30 mm shorter, 49 mm slimmer and 377 g lighter than the X-H2S.
Drawn to scale from the makers' dimensions (W × H × D). Front shown, depth on the slanted edge.
X-H2S — Sports, Wildlife & Professional Video: The fastest Fujifilm ever made — 40fps, 4K/120p, and subject-detection AF that redefines what APS-C can do for action photography.
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.
