I was playing with too many variables this morning, but I’m learning more about using the Pro Capture H mode, shutter speeds, etc.  This was made at 1/30 sec. shutter speed with the Sigma 56mm f/1.4 lens which seemed to be the slowest I could use in Pro Capture mode.

I was surprised at the apparent recording of the “step movement” of the tail feathers since this was only one 1/30 sec. exposure.  This image is a crop which has been enlarged.
