Just playing with the new 400 5.6 today and got this little guy who posed for me. I like the light and the jpeg straight out of the camera was pretty good I think. THis was handheld as well. He is not an amazingly colorfull bird but this little guy visits daily. I am pretty sure it is the same bird, he goes to the same spots all the time.
