GearScore™ Verdict — Which should you buy?
Street & Travel — X100S (2013): The X100S was the moment the X100 series became legendary. Dramatically faster phase-detect AF, X-Trans II image quality, Fujifilm's film simulations, and the iconic hybrid viewfinder in a pocketable fixed-lens body — the blueprint every subsequent X100 has built on. A brilliant used-market buy for street and travel photographers who want the Fujifilm experience at an accessible price.
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.
