The GF mount lenses are for the Fujifilm medium format camera (e.g. GFX 50 or 100 models). The format has a focal length equivalence (to 35mm film) of 0.79x. Fujifilm launched this format with six lenses, three of which were available at first shipment of the body, two of which became available later in 2017. Since then Fujifilm has regularly added a lens or two each year:
