The other day I attempted to fix the stuck open aperture on my CZJ 50mm, in the process I took off some parts and when put back together the infinite focus does not work. How would I go about ficing this?
Simple answer is reassemble the lens properly, but this information is obviously of no help to you. So please describe/list what you did to the lens in attempting your repair. We have too many variables here at the moment - an element could be positioned incorrectly, the helicoid is positioned wrongly or simply a scale is wrongly positioned etc. The mode of failure depends also on the lens type, so please indicate exactly which lens this is and what mount.
Given this information you will soon get a helpful answer from this Forum.
