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.
Low-Light Video, Documentary & Available-Light Filmmaking — A7S II (2015): A landmark in mirrorless history — the first Sony with IBIS and internal 4K, its low-light video capability still impresses today at a used-market price.
