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.
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.
