My first try of quick photo-guide (BRunner's quick repair photo-guide Wink) . This Sonnar is not hard to service (except optics and aperture, the front group is accessible only from front - you need to remove the nameplate ring) Sorry, no step-by-step guide, just considerable cases. I forgot to take shots of some screws, I try to describe it in comments. I present only the assembling process, dissassembling is just reverse.




Put in place the screw which transfers motion of aperture ring to aperture blades.








Put in place the screws which holds the slide-ways shown in previous picture. Now you can adjust infinity and then mount focus ring which limits the focus range.

I will add more lenses later. Isn't big delay to take few shots during the process. Next in queue is Jupiter-9, Trioplan 100, Sonnar 135 MC and more.
