Roy just reminded me about the aperture settings
In AV for the absolute sharpest photo with the 170-500 if the light will allow it, is f10 if not then try the various f stops going down to f5.6 to get a reasonable speed.
It is only recently that I found the optimum setting for the lens and now I find I am getting even better results and less throw aways if I can keep it around the f10 mark.
Check out my Gallery on BF for the ISO, Fstop, speed.
