I had to shoot an event inside a dimly lit room. It was a large room, probably 100 x 100, with ceilings at least 20 feet high. Sort of like an auditorium.

I used a 7D and a 70-300 L, with a 430EX mounted on the camera. I've never shot a zoom, indoors, with a zoom lens/speedlite combo.

I got quite a few shots with red eye. Easy enough to fix.

I had a couple of Pocket Wizards, and would have been able to move the speedlite off to the side, but I had only two hands, and no one else to hold the speedlite/PW.

Is this typical to see red-eye with a zoom/speedlite combo?
