I hit your eagle with a little noise reduction and sharpening... to give the image that "penetrating" look. Nothing more. It seems the TAMRON SP AF 200-500mm f/5-6.3 may be a bit off in focus. It should be a more "on target" shot. Do you get better results when it is on the a300?

Look, I did not create the optical laws of the Universe ... I simply learned to deal with them.
Remember: It is usually the GLASS, not the camera (except for moving to Full Frame), that gives you the most improvement in your photography. flickr® & Sdi
