GearScore™ Verdict — Which should you buy?
Professional Sports, Press & Wildlife Photography — D6 (2020): Nikon's final and finest DSLR — the D6 brought 105 all-cross-type AF points, 14fps, and built-in LAN to the F mount. The last word in optical viewfinder photography.
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.
