Well, I managed to get the focus to go to infinite, and the arpeture works just fine. Took me about 2 hours, but in the end all is well... except.. Now I have an issue with the mount ring. Specifically, the lever that stops down the aperture blades is extremely stiff. The lever will not move unless I physically move it myself. The aperture step down pin from within the aperture assembly is working fine by the way. But between the spring on the mounting ring mechanism, and the spring pulling back the pin from within the arpeture assembly, both will no reset the arpeture lever on the mounting ring. (Sorry, I am no doubt using part descriptions, but I hope you get the general idea
The mount ring from what I understand, consists of two parts: The outer ring, that connects to the camera body, and an inner ring. By removing the shorter screws from the mounting ring, the two pieces will seperate. It is my understanding that there are ball bearing between the two pieces. I have not as of yet, seperated these two pieces. (A bit gun shy, you might say) . I am assuming at this point that the ball bearings are being pressed or compressed? I tried backing off all the screws and bringing them back down evenly and in rotation. I am able to get them all down, but not particularly tight. The mechanism will work, but getting them all down tight is proving to be an exercise in minute adjustments. Am I on the right track here, or is symptomatic of some other issue.
Is there some magic involved here, or is this lens indeed possessed?
