Fuji 100mm F3.5 AE Lens (6X9) adapted to Pentax (35mm)

It is a lens designed for medium format cameras (6×7 and 6×9) of the Fuji brand, which began to be marketed in 1974. It has a classic Tessar optical design, that is, 4 elements in 3 groups, which results in a high contrast due to low number of elements. At full aperture you get gorgeous bokeh in the out-of-focus areas, and at other apertures (especially between F8 and F11) it’s fabulously sharp in the center.
