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.
When I have shot in film commercials for television and music clips with an Aaton XTR camera and Super 16mm format, I have always used negative film to be able to balance the lighting of the different shots. But when it comes to photography I prefer to work with reversal film, whether it’s color or black and white. There is something special about the slides and I like to see them in a light box, or projected on a screen where you can see all the richness of the image.
