After a horrible week of weather in Socal of all places!!! I finally had a chance to use my new
400mm f/5.6L. All the shots were taken wide open and I was very impressed with the sharpness. The focusing speed and tracking is like lightening compared to my old 100-400. Let me know what you think of this American Avocet. I was flat in the mud to get this one and I got some stares but I think it was worth it :).
Taken with 1DII
at 1/3200 and f/5.6. ISO:640. With Fill Flash at -1 2/3 ( I think)
