Input:
I bought a group of lenses and had no intention of keeping this one. I popped it on an old D50 to test it out and simply fell in love with the optics on this thing. I don't really have a true use for it, but I think I might have to find a way to keep it. This is the only prime lens I have ever gotten my hands on and I can see why they demand such high prices.

It is rather antiquated technologically which is why I almost gave it a 4 star but the glass is what you pay for. I am actually considering selling my D60 and promoting my D50 body just so I can keep this lens. In reality I need a more capable body anyway, but investing in this kind of glass makes more sense in the long run.
