Nice image you have hear, with perfect BG. I noticed the AI servo used. With such a static subject, one shot AF would be a good choise but maybe this is what you have learned to use.
It's a wonderful shot, great IQ, contrast, color; and the bg is indeed perfect. Someone elsewhere in the forums has been asking about IQ for the Sigma 50-500 at the longer focal lengths. This would appear to be a pretty impressive answer to the question.
