Description:
Adapted to K-mount via extension tubes and home-made hard felt retaining ring inside extension tube. Searching for a dead Werra camera mount in order to possibly have an external aperture ring.

6 blades, 49mm diameter filter
f/4 to f/22

To have a "correct" registration distance, I have used thus far about 22mm of tube with the lens inserted (see image).
Mount Type: Non-Pentax Mount

Bonjour,

Yet another "Franken-lens" creation ... Found a Werra Rangefinder lens at my thrift store: a Jena (Carl Zeiss) Cardinar 100/4 in decent shape, but I do need to pull apart the glass and clean up some minor haze/fungus ... still quite usable.

Tubed it to about 22mm to have a "correct" registration distance ... this was all trail and error ... and re-try again. Here are some early sample test shots ... wide open or near ... the second one is with additional tube length added.

Allez et salut, John le Frog
