Fantastic work! I always envy anyone with a lathe at one's disposal
The point of including the fixed rear element is very obvious on the original lens once you take some shots and examine the images with/without the elment in place. Unless you are into dreamy hazy images, you will have to close down seriously to make this FAST lens usable . This is similar to some other lens with fixed rear element, e.g., FD 55/1.2 Asp, FD 50/1.2L.
But since your second-last element is not original, the optics is altered. So who can say for sure? Good luck in this adventure!
This is the second FD 85mm f1.2 L i've bought...Unlike the first one, which had both rear elements missing this one has mint optics but its been tampered with inside as the circlip between the the two halves of the helicoid was badly damaged and the aperture actuation lever was 180 degrees from where it should be so it was'nt stopping down when I first received it. I got it to stop down ok but the circlip was beyond recovery...Does'nt seem to effect the workings of the lens with it removed though so I'm not too worried.
Interesting what you say about the dreamy hazy images without the fixed rear element in place...I have'nt actually taken any sample pics with it yet as I only finished it late last night and had to go to bed early for work today so I will have to take a few samples to confirm that...It looked very sharp through the viewfinder last night though, even wide open.
