that is my thought exactly. I'm thinking of sticking with an F or getting an F2 and getting an F5 for AF/more modern lenses. I think selling one for the other is too hasty of a decision...I might prefer MF and in that case I have a camera to fall back on with it's contemporary lenses. I would get the 50mm f1.8 D lens for my AF 50mm. I think most 50mm's are good enough and I do not need anything faster than f2.0 so no need to overspend on a 50mm.
