Did you get infinity focus by shaving the mirror?

Where did you get it converted to EF?
Thanks

Converting it to EF is quite easy as the bore of an EF mounting plate is large enough to take the 47mm diameter rear bezel plate that holds the fixed rear element...However I am planning to convert one to Sigma SA mount, which has the same registration distance as EF but which only has a bore of 43mm and therefore that is going to make it far more complex.
Converting the Iris over to fully manual operation was easy but converting the mount wont be. I will almost certainly have to machine down the diameter of the rear bezel plate to fit, which sounds straight forward enough but that might remove so much material that the bonded fixed rear element, with a small ring of metal around it will end up seperated. That means I will probably have to fabricate a new rear bezel and screw or bond whats left of the original bezel containing the fixed rear element to it...And that could spell accuracy problems with the moving rear/fixed rear element distance and the registration distance needed to reach infinity.
My first 85mm f1.2 L came with both rear elements missing so I have now purchased a second "donar" 85mm f1.2 L, with a stuck open Iris, to supply the rear elements for mine.

I love it
I want one

Great light and color to the first 4 images,
I think this says more about the photographer than the lens
you do nice work.

Best

I finally received my second FD 85mm f1.2 L. Immediately after getting it out of the box I found that all the elements were there and in seemingly perfect condition but that the Iris was stuck wide open, so I stripped it down to investigate.
Turns out that someone has been fiddling with it before as several screws were missing and a large circlip inside was badly bent. After pulling out the circlip and removing the helicoid I discovered the problem was the Iris actuation ring/lever was about 180 degrees away from where it should be stopping it working the little Iris actuation cam...Someone had obviously been tinkering inside and did'nt know what they were doing. One of the helicoid stops was preventing me simply turning it to the correct position but as these were loose at this point I simply lifted out the offending stop turned the ring and replaced the stop. Now I could reassemble the lens using my converted aperture dial from the first lens to manually control the Iris.
Now that I have been able to examine and measure a complete version of this lens I have been able to start working out exactly how to convert it to SA mount.
BTW, the fixed rear element is actually removable, not bonded in permanently as some may have thought. However, it is bonded into a very thin, fine-threaded ring which screws into the rear bezel. Luckily mine was'nt too tight so I could easily unscrew it and remove it for safekeeping whilst I work on the bezel.
Looks like I'm going to have to turn down the outer raised rim of the aperture dial retaining ring then I will have to turn the rear bezel in my lathe to produce a flat ring containing the fixed rear element retaining thread surrounded by a few mm of material to enable it to be fixed down. I will then turn up a new custom bezel from Aluminium and this ring will either be screwed or bonded, with expoxy, into place on the new bezel. Thats the plan anyway but the hardest bit will be finding an accurate way to hold the original bezel in the lathe without crushing it as its made of very thin Aluminium and therefore it is very easily deformed. Its not going to be easy thats for sure.

Looks like a sweet lens.
The only real negative about my 85LII is the focus by wire, there is no friction when you turn the focus ring which makes it a bit twitchy.

Alf,
congratulations! You can make (with your lathe) a rear element holder from an old M42 mount or body cap. I epoxied the rear element inside such a thing and screwed the assembly inside an M42-EOS adapter, before I epoxied them together as well, after fine tuning for infinity.
Just make sure the inner diameter of this male M42 threaded piece at the lens side is wide enough ( = the rim of the M42 thread itself is thin enough). Otherwise the moving lens group may collide with it, instead of moving inside. At infinity, the moving group comes very close to the stationary element.

Hi guys. After the initial conversion work on my FD 85/1.2 L about a month ago, it would only focus to about 4-5 feet away on my Sigma SD14. However I decided to try and convert it for a second time but, using a different approach and it now focusses to about 15 feet away.
I know thats a very short distance compared to what some of you EF guys have managed, but I think its plenty far enough for portrait work...In any case, I dont think I can get it to focus any further away that.
Heres some pics I took with it today, all at f1.2 and using ambient light:

I took with it today, all in ambient light and wide open at f1.2:
