X-S20vs A6700vs A7 III
Which should you buy?
Hybrid Photo & Video — X-S20 (2023): Fujifilm's most accessible X-series body — 7-stop IBIS, 6K video, 20 film simulations, and a user-friendly layout.
All-Round & Video — A6700 (2023): Best-in-class autofocus and 4K/120p video in a compact APS-C body — the standout camera under £1,000.
All-Round Photography & Video — A7 III (2018): Still one of the best all-round cameras money can buy — particularly strong used. The A7 III proved that full-frame doesn't have to mean compromises, and nothing at this price point has meaningfully beaten it.
