The Super-Multi-Coated Takumar 135mm f/2.5 (s/n 43812) is a telephoto fast lens with a multilayer coating and 18° field-of-view (FOV). It is widely used for shooting distant objects and portraits.
Released in 1968, the Super-Takumar 135mm f/2.5 (p/n 43801) does not have much in common with its third and the last replica (p/n 43812). The optical scheme had been considerably revised , the lense weight had changed.
The Super-Multi-Coated Takumar 135mm f/2.5 (p/n 43812) is remarkable for its reliable construction and exellent optical characteristics. With aperture wide open, it is in a portrait way soft, very sharp in focusing area with a slight vignette. However, with aperture closed at one half- stop, it provides exellent sharpness and microcontrast in the frame. The image it produces is up to f/5.6 soft.
It is equiped with an instant-return diaphragm with a mode selector. In outward appearance, the focal depth scale, starting with 4, sets the lens apart its namesake (p/n 43802). It came with the Takumar 1:2.5,135mm 1:4,200 mm .
It is considered up to now to be one of the best medium telephoto lenses. In many ways due to the arrival of such lenses, the legend, named Pentax, arose.
The build is metal. The aperure ring with a one-half-stop f-number scale (from f2.5 to f16).
