Up at sunrise this morning to shoot some birds and testing the Nikon D4 with the 300mm f2.8 AI-S with TC-301 2x converter (600mm f5.6) for all but the first shot (taken with 50mm 1.4G).
Thanks! It's a favorite of mine as well. Also something to keep in mind is that these shots were all done using manual focus with no assist (no time to look at the assist indicators in the viewfinder).
