Topic: What stops the focus on a CZJ Flektogon?

I have a 35mm F/2.4 and I'm having difficulty figuring out how to reassemble it so that the focus is limited on the macro end, rather to have the lens screw out of the barrel.

Any ideas?

Re: What stops the focus on a CZJ Flektogon?

It's a multi start thread, if you screw it together in the wrong position then it will either become detached when close focussing (as your is) or fail to reach infinity at the other end. It is just trial and error, take the barrel apart, turn it a few degrees and screw it in again. Eventually you will find the right position.

In future mark the position where it becomes detached when you disassemble it.
