I just want to add to my previous review of the excellent optics of this lens, that it would be nice to see the TRUE MTF data for this lens, because what is shown here in the "MTF data" is actually results of testing old Nikkor AF 300mm/4 lens, not the AF-S new version. Just go to the old photodo site and look at AF 300mm/4 Nikkor, it is exact the same data which was just copied for new AF-S version without any comparison and testing.

This is my favorite lens for wildlife photography. Both on my F5 and D200 it is very sharp (little bit less sharp, than AF-S 300/2.8, but still great and for much cheaper price). It's also much lighter and a pleasure to use in the field compared to giant Nikkor AF-S 300/2.8 or AF-S 200-400/4. It's sutable for action and focuses much faster, than slow Nikkor AF 80-400 VR zoom.
With Nikon Teleconverter TC-17 attached, it's slow focusing, but autofocus works fine and results are very good.
Great lens, the best money/quality value.

Very nice lens for almost any tele work.
