My girlfriend graduated today and I thought it would be nice if I could get a shot of her walking the stage in addition to the one provided by the official photographer. Well, despite the constant reminders that friends and family were not to approach the stage for photos, I found a nice little spot near the stage and put on my 70-300 IS USM. Not ideal for the lighting, of course, but I was close enough so flash would compensate.
I fired a few tests on other people. Perfect.
My girlfriend's name is called. She's walking across the stage. She's all framed up. Click. No flash. Click. No flash. Click. No flash. Three perfectly framed shots all but useless because I was shooting at 1/60 at like 200mm and there wasn't nearly enough light.
I figure the battery is dead. I already learned the hard way that these things don't indicate when battery power is getting low. Okay, whatever. Give it a few minutes. A buddy of mine starts walking the stage. I decide to try shooting him just to see what happens. Click. Flash. Perfect (for me) photo.
I shoot 5 more shots in quick succession. Flash fires each time. Battery dead? I don't think so.
Someone want to tell me what went wrong at the exact moment I needed the thing to fire?
