O.K. Here is my first shot with my new Sigma 150-500 mm lens. I shot in Raw, hand held, ISO 200,1/400,F 11, at 500 mm. Very nice lens.
Very nice. Your shutter speed is calculated to show just a bit of blaring in the blades. At 1/500 sec. you would probably have frozen them, which loses the impression of movement.
