Re: lens repair, modification and disassembly guide thread
Having read through all of the pages in recent days, I somehow escaped the comments that your G28 -> MC PF 55 Frankenzeiss conversion did not have helicoid focussing, until after I had ordered a donor 55 f1.7
The helicoid in the 55/1.7 is used to focus... I\'m not sure what you mean...
AFAIK, Sebboh\'s engineering drawing for the G45 still requires a couple modifications, one is to add some thickness to the back edge to hide a gap when the lens is focused to MFD.
The other is to change the location of the screw holes that the LTM to M-mount adapter use to secure it to the rear ring, one of the holes lands on the 6bit location.
