I see. You're right--$200 and the hassle just wouldn't be worth it! And it doesn't mention anything about using Canonlenseson a Nikon body, so perhaps it's simply impossible.
Oh well--I'll probably be plenty busy figuring out all the little details on the D50 for a while, so perhaps I shouldn't be in such a hurry to get the macro anyway.
