Harold, the 80-320 at the long end is not much better in the center than at the corners, and it doesn't improve a lot by stopping down either. I think it's a nice lens just by this consistency of image quality. However, I don't think that above 200 mm it'll fit the sharpness requirements of the *ist d sensor (60 lppm).
