Particularly on longer lenses like the 500.
I've googled this and haven't found anything useful.
I don't think there is much difference if any in the auto-focus itself or the optics, but the AF-S II lenses were redesigned with e.g. carbon fiber to be lighter.
i believe the barrel on the AF-S II is made of a magnesium alloy as opposed to aluminum in the AF-S I. That took some weight out of the lens. Additionally, I believe the AF-S II have a shorter minimum focus compared to the AF-S I. I think those are the only significant differences.
(sorry couldnt help it) Greg is correct
I don't own any of these, but isn't it the case that it's only the marked minimum focus distance that's different? Ie both an AFS-I and AFS-II will focus on the same object at the same minimum distance, but the AFS-I is marked with a longer minimum distance on the barrel.

As I remember, magnesium in place of aluminum and MFD.
OK, I guess that was one of the other lenses that got upgraded, then.
