Kestrel Hunting

We frequently see this Kestrel perched in its favourite tree looking out for mice in the field adjoining our house. With the sun shining this morning (a rare event this winter!) I took the opportunity to take some pictures to try out the Canon 7D camera, fitted with the Canon 100-400mm lens.

As the tree was moving around in the strong north easterly wind, I experimented with "AI Focus" which  re-focuses the picture if the subject moves. It seems very effective! I am also using "ISO-AUTO" more as it adjusts the ISO automatically (depending on light levels) to achieve a 1/500 to 1/640s exposure at 400mm, giving far less camera shake.
