There's some specific info about the 1.2. The rear element of that lens is surrounded by a slotted ring, I think that after removing that one you get access to the inner which lets you take out the module.
My only experiences with delicate lens cleaning ended very bad, so I didn't want to put my dangerous fingers over that glass, it was meant for somebody else

Joe,
No, I've never used a hood with my 50/1.2, even though I have one of the hoods that were specifically made for this lens (mint too, probably would bring a small fortune on eBay). I've never experienced flare, at anytime, though I do admit to avoiding high-flare situations (shooting into the sun).
As for how to take apart the 50/1.2 from the rear, i wrote this several months back:
"The 50mm F1.2 is very simple to work on. If disassembled from the rear, just unscrew one retaining ring with a lens spanner and the entire focusing mount and distance scale part of the lens comes off in your hands. No need to worry about scribing anything, it only goes back in one way (has a notch which lnes up with a metal "block" on one side of the interior). The rear most lens group can be unscrewed using two fingers which exposes on more retaining ring. Unscrew that with a lens spanner and the lens group that sits immediately adjacent to the aperture comes off. For some reason, the rear element that sits next to the aperture blades tends to fog up on my lens over a period of about a year (hard to believe that a 40+ year old lens is still outgassing but I guess it is). I've forgotten the amount of times I've cleaned this one element, thankfully it's something that is easy to do and can be completed in about 15 minutes. The coatings seem to be hard as nails, I've never had a problem with scratching anything or with wipe marks. Why spend $75.00 to clean a lens (at least this one) when you can do it yourself?"
Hope this helps,

I ordered a spanner wrench today, camera repair book, and am bidding on some courage over at the bay.
God save me......
