Whats the verdict on the 24-120 VR lens as a general use lens? I am mostly curious about the quality of the glass and the image quality. I know the VR is great but what about the rest of the lens. How does it compare to the other Nikon zooms in that range? I am also looking at the 24-85. It seems like I read the 24-85 is a little sharper and it is about half the price. Please give me some help on picking a general purpose zoom for a F100.
