I bought a broken Braun Super Paxette II BL camera, but the purpose of the purchase was the four lenses that came with the camera. One of them is the Staeble-Telexon 1:3,8/135.
This is a lens from the 1960s.
As expected, the Telexon has the M39x1 mount with the flange focal distance of 44mm, it is indeed for a Braun camera. And it has a rangefinder coupling.
The minimum focusing distance is quite long, just a bit less than 3m.
The optical design of the lens is known. It has 4 elements.
And two front elements are cemented.
The optical design is similar to the Wrayflex Lustrar 90/4:
The aperture has 10 blades:
The aperture ring has click stops at f/3.8, f/5,6, f/8, f/11, f/16, f22.
The filter thread is 52mm, it is easy to find a suitable cap. And while I am used to very compact Staeble lenses (35mm, 85mm), this Telexon is quite long.
The Telexon 135/3.8 (on the right) and the Pentax M 135/3.5 (on the left):
Unfortunately, this copy of the Telexon is not in good condition. There was fungus on the optical elements. I removed the fungus, but its imprint is still visible. Maybe the lens coating is damaged or the fungus has even etched itself into the glass. However, that doesn't stop me from using the lens.
