Bob, focus is primarily pre-focusing (home plate, first base,
etc). Is the depth of field shallower than a conventional lens at
the same aperture? Toronto's baseball stadium is domed, and though
it is retractable, 80% of the games are at night under artificial
light.
Exposure at Rogers Centre (formerly SkyDome) is around 1/1000 f4 -
5.6 with ISO 1600 under the lights.
No, depth of field is the same as a refractor lens at the same f-
stop. It might work for you.
