A6700vs A7S
GearScore™ Verdict — Which should you buy?
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.
Astrophotography & Low-Light — A7S (2014): The original A7S pioneered the concept of a camera optimised entirely for low light. Its 12.2MP sensor has enormous photosites — extraordinary high-ISO performance that still holds up. Lacking IBIS and limited to 1080p internally (4K requires external recorder), it is a specialist tool. For astrophotography, event videography, or any scenario where light is genuinely scarce, it remains outstanding.
Who should buy what

- APS-C photographers who want the best Sony autofocus in a compact body

A7S (2014)
