I have been looking at one of those. Don't you have to have it converted before you can use it on a D800?
Ben got me hooked on the 55 f/1.2 quite some time ago. I first bought the last version of the lens, an AI. I mention that simply because if you want this focal length and speed, you can get it without having to worry about converting the aperture ring. The optical formula of the AI is the same as the pre-AI S.C. I did sell my AI lens to a person on this thread who hasn't posted in some time, then bought a very clean copy of the older S.C. lens that had the Nikon AI conversion kits already installed. I did that not because I expected better performance but because I wanted to experience shooting with an all metal lens with a scalloped focusing ring. I bought an EX+ lens on E-Bay for $375.
Unless you're absolutely committed to a pre-AI lens, I'd suggest you stay away from them. They can become very addictive, as I've recently noted. After buying that first lens I quite remarkably bought another FOURTEEN of them. They are beautiful to look at a pure pleasure in the hand. I count the 55 f/1.2 S.C. AI'd as among my favorite lenses.
I note that KEH has an AI version in EX+ condition for $479 which is more than I paid but for what they offer in terms of warranty and service that might not be a bad way to go. They list an AI-s version which simply doesn't exist. They have a converted S lens, but that is an earlier version that did not have the "coating" which appeared in the S.C. The S.C. they have is not converted and there are no conversion rings available for this lens, so it would be necessary to cut down the aperture ring. I don't recommend that to my friends, but I know others on this thread feel differently about that.
Kit building is forever Dave. The only question is how much money do you want to spend to add lenses...
