Sony A7S Sony A7S (2014) Starting from £600 new Best for Astrophotography & Low-Light View A7S

GearScore™ Verdict — Which should you buy?

Landscape, Studio, Commercial — Z7 (2018): 45MP full-frame in the same body as the Z6 — choose your priority.

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.
