GearScore™ Verdict — Which should you buy?

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.

Travel & Versatility — Sony RX100 VII (2019): The most versatile compact camera ever made — 24-200mm zoom, 20fps burst, and 960fps slow-motion in a jacket pocket.
