Verdictwhich should you buy?
X-S20 — Hybrid Photo & Video: Fujifilm's most accessible X-series body — 7-stop IBIS, 6K video, 20 film simulations, and a user-friendly layout.
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.
