There just isn't much wildlife around today...maybe they are laying low because the wind is blowing so stringly.... I did find one goose holed up in the back end of a cove and I popped a couple to try a static shot....this is with the 500AFSII and no TC. Honest opinions on sharpness? I'm working on a cheesy LCD monitor at the moment here at work as my CRT croaked a short while ago and I can't really judge this. The focus lock was at the base of the neck where the black stops.
