Carl Zeiss Jena DDR Tevidon 2,8/70

I've just got three old Tevidon lenses 1,9/35, 1,8/50, 2,8/70. These are film C-mount lenses with register less than 18mm. It means that they are usefull with Pentax only as kind of macro. Eg. focus distance for 2,8/70 is about 15cm.

These lenses are used by users of micro 4/3.

So for Pentax it is just for fun. Interesting thing is iris shape which is regular triangle at f11

wide open f2,8

probably f11
