David: I seem to understand what you just described. However, I am not sure about your description of adjusting the focus (4th para). If I may rephrase, this is what you are suggesting: 1. Screw in the lens elements securely. 2. Adjust the infinity focus using some form of a collimator but only by turning the lens focusing ring on the lens barrel. This is exactly what I did initially to verify the focus. The only variables that I can see are the lens elements' position and the focusing knob. The former are fixed in your method. That leaves the focusing knob. When I tested the camera's focus, infinity was being focused a bit before the knob reached its end. So infinity was being focused a bit prematurely. That is what prompted me to tweak the position of the front element. Perhaps there is something else that I am missing? I did take out the lens mount from the body, cleaned a few things in the shutter and reseated it back as it was before. Or have I missed something completely in your post? |
