GearScore™ Verdict — Which should you buy?
Street, Travel & Everyday Photography — X100F (2017): The X100F is the camera that made the X100 series legendary — 24MP X-Trans III, a hybrid viewfinder, and the best fixed 35mm compact lens available.
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.
Who should buy what
X100F (2017)
- Street photographers who want a discreet, tactile camera with a fixed 35mm lens
- Travel photographers who prefer one lens and minimal kit

A7S II (2015)
- Filmmakers and videographers who want legendary low-light performance at a used-price discount
- Documentary shooters working in unpredictable available light conditions
