Nope. Dumb thing to want to squander your money on. Save it for when the water heater or well pump goes out. Or take your wife out and tell here you're thankful for her. What in tarnation do you need such a frivolous lens for?
I've used both lenses in low light situations. In my opinion the 50mm f/1.4 Nikkor (any version) is a much better lens wide open, but they're both fine when closed down a few stops. Of course, you would think you'd buy the faster lens for the wide-open performance but that's not the case here.
I just wanted to add onto my previous comment, If you do plan on shooting a lot at night, then something of this sort is useful. Focusing is easier as it lets in more light, you dont have to push your film as high, and you can use a faster shutter speeds to get the same exposure. The lens maintains its price fairly well, and I know the 50mm version is used by digital film makers too. The 50mm is one of the few AIS lenses still produced new by Nikon.
I've never had a f/1.2 lens, but I have owned Nikon 50 1.4D and 85 1.4D. Wide open they were so soft and color fringing was terrible. I eventually sold them. I later ended up with the 50 1.8D and 85 1.8D and that's the ones I have today. They were a fraction of the cost of the 1.4's. And I'm very happy with them. Personally, I don't think a super fast lens is worth the money.

OP has already decided not to buy it, so there is no point in shelling out our thoughts any more.
Haha, yeah, right. Here I go.
I would love to have that lens. It's not sharp and it produces all kinds of artifacts, plus it's expensive. But I think the preferred nomenclature is "lens with a character". My only problem, or "problem", is that I already have lenses with similar character even if at different FL. On top of that, my 50/1.8 AI and CV 58/1.4 are perfectly capable 50s. Unless someone offers it to me for very little money, I probably won't own it any time soon. OP, on the other hand, should definitely get it.
