I thought I would also include the worse case scenario of the day. A black subject that was in shadow with bright, harsh light in the outer area. I initially grabbed focus pretty fast, but then recomposed as the bird continued to move. The further it got into the shadow, the more hunting the AF did. When I got focus confirmation, I shot, but the picture was NOT focused right, as both the original and the crop show. I jumped to ISO 1600 to get this one (most are at ISO 500 or less) so that should tell you how reduced the original light was for the middle of day. This is pretty ugly...
