Canon 7D with 500L f4 lens with 1.4 II extender @ 1/1000, f8, ISO 400, exposure compensation of +1 because of the background sky.

Cropped for composition purposes. Background untouched. I had to blend away a small halo around parts of the bird due to contrast between bird and sky after sharpening following reduction of file size to 72 ppi.

Cheers,

Mike
