GearScore™ Verdict — Which should you buy?
Enthusiast Photography, Travel & Street — X-T30 III (2025): 40MP resolution and flagship-level subject detection in the most affordable X-T body — the best value Fujifilm camera ever made.
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.
