Tested and fully functional Tokyo Kogauk 28mm f4 lens
The UV mount lenses from Tōkyō Kōgaku were produced from the 1960's specifically for the Topcon Wink Mirror S and Topcon 100 Auto/Uni, and further used by the Unirex and the 1970s IC-1 Auto.
These unique lens designs do not have an aperture setting ring, as this is found on the camera body. The maximum aperture of the lens is "dialed-in" to a camera body mounted control when the lens is first fitted. This sets a maximum aperture parameter for the camera's exposure system. All Topcor UV lenses have a common minimum aperture of f/22.
UV stands for Ultra Violet, as the lenses had a UV coating, and did not need a separate UV filter.
