I considered suggesting the same thing, but "- turning off flash,
shooting manual exposure mode" ...
If it was a problem with P-TTL shouldn't the shutter have triggered in
manual exposure with no flash?
Unless maybe the camera software just got scrambled & didn't
clear right away.
Christine,
Did you take the battery (or batteries if you use the grip) out during
troubleshooting or at home before testing the camera again?

I love the shot.
Can't help specifically with the system glitch, but I wonder if
there's any chance the flash was the problem. The camera might be
waiting for signals from the P-TTL logic. Sometimes it helps the
wireless stuff if you add a reflector of some sort (eg tinfoil) to the
popup head to get more light over at the remote 540. I have even had
success holding my hand at an angle near the popup.
Honestly, I've just switched to using cheap radio triggers for remote
flash. All my random flash failures went away.

Hello all,
Here's a head-scratcher:
Tonight, I was shooting senior portraits of my son. We had gone out
to the track at the high school, a place he holds quite dear, for the
occasion. As the evening grew darker, I had my flash (540) set up on
a stand & softbox, firing with the camera's wireless remote system.
All was fine, more or less, for several minutes. Until the camera
stopped shooting. I would press the shutter, and I'd get a flicker of
light (focus assist or pop up flash signalling the 540? not sure..),
but the shutter wouldn't fire. Several times I would re-focus and try
again, but nothing. I tried the following:
- turning the whole thing off & on again
- turning off the focus assist light
- setting the AF to release priority, instead of focus priority
- using manual focus
- turning off flash, shooting manual exposure mode
- shooting in Av, Tv, Tav, P and AUTO
None of these got the shutter to fire.
We packed it in for the day, and when I got home, 20 minutes later, I
tried the camera again. Worked fine, in Av, M, Tav, etc... though I
didn't try it with the wireless flash again... Mind you, this whole
shutter mechanism was recently replaced (6 months ago) at CRIS. So,
I'm thinking I must be doing something wrong, or at least missing
something. What do you make of this? Any thoughts?
Lastly, just for fun -- a peso. My son, Nick, from tonight. Looking
as bad as he is able...
