With a very long lens, and particularly one with a maximum aperture
in the f/5.6 range or smaller, it's probably not accurate enough to
rely upon. Make sure the focusing screen is properly focused to your
eye with the diopter control, and then learn to get the best focus
point by watching the out-in-out of focus transition and practicing.
Oddly enough, I've found that I'm very happy with the focus
confirmation with longer fast lenses, provided I've picked the right
thing to focus on. The viewfinder of the DS2 sadly does not have that
same 'snap' that my ME Super had, and I've been using the confirmation
as my 'snap'.
Generally I'm shooting wide open. Usually I use the belt buckle of the
batter at home plate or the MLB logo on the base, or something similar
with high contrast.
