Leitz Wetzlar Elmaron 150/2,8

Interesting projector lens from Leitz. I tried Colorplan 90/2,5 and Hektor 10cm/2,5 including this lens, all have different style.

taken with Gaumont Kalee 70/1,8

The same advantage is (if) you found it include the focusing mechanism. One thing for sure all 3 were made for different projectors. Colorplan was for Pradovit, I dont know about this one yet.

This Elmaron has similar results with Hektor, but better handling strong light.

Using Lensturbo and NEX5
