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.
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.
