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. The first one is the Staeble-Telexon 135/3.8. Another one is the Staeble-Lineogon 1:3,5/35.
This is a lens from the 1960s (or 1950s?).
As expected, the Lineogon has the M39x1 mount with the flange focal distance of 44mm (for a Braun camera). It has a rangefinder coupling.
The lens has 4 elements.
It is assumed that the Lineogon has the same optical design as the later Novoflex 35/3.5:
It is a retrofocus modification of a triplet: 4 elements in 4 groups.
Now I have two 35mm lenses for the Paxette series:
The triplet (3/3) Staeble-Werk Choro R 35/4.5 (on the right) has a much more protruding rear than the retrofocus (4/4) Staeble-Lineogon 35/3.5 (on the left). The goal of retrofocus is to move the rear optical element far out of the film plane (for example, to place a mirror or a leaf shutter). Increasing the number of elements also makes it possible to make the lens faster (f/3.5 vs. f/4.5) while maintaining image quality.
The aperture has 10 blades:
The aperture ring has click stops at f/3.5, f/4, f/5,6, f/8, f/11, f/16.
The filter thread is 40.5mm. The front part of the lens (with the filter thread) rotates during focusing. The minimum focusing distance is about 1m.
The front (threaded) part also rotates when the aperture is changed. Therefore, removing a cap may inadvertently change the aperture setting.
This lens is not as exotic or rare as the Choro 35/4.5. However, it is interesting for me to use such an old lens.
