GearScore™ Verdict — Which should you buy?
Portrait, Street & Documentary Photography — GFX 50R (2018): The most portable GFX camera of its era — 51MP in a rangefinder-style body for photographers who want medium-format quality with a more discreet form.
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
GFX 50R (2018)
- Photographers who want medium-format quality in the slimmest GFX body available
