JDMvW Posted October 9, 2016 Share Posted October 9, 2016 <p>There are a ton of repair instructions available through a Google™ search:<br> <a href="https://www.google.com/search?num=100&newwindow=1&q=fd+55mm+f%2F1.2+repair+manual&oq=fd+55mm+f%2F1.2+repair&gs_l=serp.1.0.33i160k1.5520.10319.0.12236.10.10.0.0.0.0.184.947.7j3.10.0....0...1c.1.64.serp..0.10.944...0i22i30k1j33i21k1.jn7okUXxmUE">link</a><br> whether any of them will help you, you'll have to find out by trial and error.<br> All of us have at one time or another learned the lesson to photograph and sketch each stage of dis-assembly.

rick_janes Posted October 9, 2016 Share Posted October 9, 2016 Mario, as far as the glass elements go you may be in luck: job one, find an optical diagram of the FD 55/1.2. If I recall right, most of the individual elements have a very distinct shape which will help you figure out their proper orientations and sequencing. Sorry, I have no help to offer on the diaphragm servicing! Link to comment Share on other sites More sharing options...
