50mm f/1.8 on a crop-sensor?
I had a friend tell me that now that I have an SLR I need to get the Canon 50mm f/1.8. I agree that something with that aperture is great for indoors, and the price is right at under $100, but since my friend shoots full-frame (Canon 1Ds), I'm wondering if I this lens is still practical for indoor shooting, since it's equivalent to 80mm on my XSi?
I thought about a 20mm or 24mm f/1.8 or f/1.4 but they are $300-$400 instead of $80.
