I agree, and that's why I asked about the sun level.......so I will bring up Axel's post of a Red Knot....simalar in tone but the specs quite different;

1/640 sec.at f8 and ISO 400 with .67EC.....compare that to your ISO 2500.....hence my question....with your f7.1 and equal EC......that puts the #s at f7.1 and 1/500 sec and ISO 400 at last light for Axel's image.....
but you were at ISO 2500 and 1/250 sec!!! So either the sun was covered by clouds or the sun was down......hence my original question.....considering I am looking at a 3 &1/3 stop difference.
