Nick,
Just added a couple of shots taken with my 300 f/4. Take a look at
this sites photos, my little album "Bill's 70-300, the two squirels
were shot with the 300 on my D80, the young whitetail on my N90s. Both
were tripod mounted, should give you some idea of the ED version. The
AF-s will be at least on a par....
