Well, just not enough lens to pull this off. The birds would not cooperate at all and kept their distance. No matter how much I played with these exposures they would not sharpen up. I was at or near max focal length for almost everything I shot yesterday. I tried everything I could think of ranging from high f stop to high shutter speed. The white birds in particular were a problem and tended to “blow out.” I could not get the clarity I wanted. Nonetheless, a good learning experience.
As for the shooter out there with the Canon 500mm IS lens, you have no idea how lucky you are I didn't roll you, steal that lens and throw your lifeless body into the slough :)
