#19
The end is in sight! On the weekend I dismantled the lens further. If I remove the last section of the outer body, I gain more than enough space to correctly fit an EOS mount for infinity focus. That body section will be replaced with two aluminium plates I'm in the process of getting cut, and I can fine adjust the distance as the donor mount had some thin spacing rings I can add to find tune in fractions of a mm. It will get a bit messy dealing with the various screw placements and also joining all the layers securely.



The aperture ring coupling I'm still not decided on. The outer aperture ring I can force couple to the inner ring. I need a new metal part made to couple that inner ring to the part that actually operates the aperture, which isn't present any more as it is part of the FD mount mechanism I've removed. I think that can be cut by hand in thin steel.



I'm getting near the point where I think I should have said stuff the credit card and just get the Zeiss in the first place...

The rear section and aperture ring is removed here. The two prongs on the left are the main control for the aperture.
