One of a small flock feeding around the fish plant at Wallace, Nova Scotia recently. D300,Tamron 200-500, hand-held. 1/400, f10.0, ISO 640. I think I was lucky to get a reasonably sharp image with these settings at 500mm, just as he paused to pick up a morsel from the surface of the water!
You have captured a very nice feeding pose with good wing and head positions. The water patterns add a nice touch and I like the blurred reflection. Since you didn't have to worry about dof for this capture, you could have chosen to shoot wide open instead of at f/10 which would have given you a faster shutter speed. The whites are a bit over. You have to be fast to catch this action...great job.
Is this Tamron lens sharp WO? I have owned super sharp Tamron lenses in the past but I have never used the 200-500.

Hi, and thanks for the comments.
The only other long lens I have to compare it with is the Nikon 80-400mm. VR, which I think is a tad sharper (although that might be the effect of the VR, since I frequently hand-hold). If I use the Tamron 200-500 on a tripod, I haven't noticed any problem with sharpness at any aperture.
