@HDNitehawk (Rick), I agree, its not that impressive.

The 600mm II +1.4x looks a little sharper, with less vignetting than the 800mm f/5.6

@Joel, I also wish the new bodies handled center AF f/8 maximum aperture, but couldn't you still use that combo in live view mode for "stationary" birds on a tripod at 1000mm-1200mm?
