I'd be surprised if DOF is an issue if you were shooting from the rear of an auditorium. If it were me, I'd do some controlled testing with the pressure off to get to the bottom of it.

Hello Paul,

Yes, off-line testing is on my agenda.

I was generally trying to get the face of one person at a time, so differing distances from the camera by multiple people was not a problem and would not bother me. Like you, I believe DOF should not be an issue from 45 feet when all I want is the eyes/face in focus. A couple of folks in this thread have suggested shutter speed my be the issue. I was shooting from a tripod between 1/60 and 1/125 most of the time and timing my shots for a pause in the action. And I can tell the difference between missed focus and blur due to subject movement. I did not count subject movement failures (only a few) in my percentage of missed AF shots.

So, yes, I need to get into the sanctuary and shoot some events where the outcome is not important to anyone.

And to be sure, I got some great photos with my Pen F and M.Zuiko 40-150mm f/2.8 Pro. It's not like the day was a failure. I would have liked a higher hit rate is all.
