Thanks to all - yes, truly a moment captured as I walked by and ran to get the camera before things changed.
Ben - ISO is a function of auto ISO (set for range of 200-6400), minimal shutter speed setting, and fixed f-stop. I would have opened the lens further but was uncertain I'd get sufficient DOF. Floor for shutter speed is set at 1/200 to, for the most part, preclude blurring from movement - not fool-proof at that speed either.
