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.
Landscape, Studio & Commercial Photography — A7R III (2017): The camera that converted professionals to mirrorless — 42MP, IBIS, and 10fps in a body that still competes today.
