GearScore™ Verdict — Which should you buy?
Studio, Portrait & Landscape Photography — GFX 50S (2017): The camera that launched Fujifilm's medium-format revolution — 51MP at a price that made serious large-format imaging possible for the first time.
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.
