I haven't had any problems as far as triggering goes, as I'm usually pretty close to the subject, or I have the flashes turned to capture the pulse.



I only use an ST-E2 to fire my flashes. I have heard so many people slam the ST-E2. I have only ever had one issue that was easily fixed, once when I was shooting the sun was beaming directly into the IR receiver on the flash keeping it from firing. So I set up a flag and it was done.


This shot was done with two 580EXIIs, ST-E2 out side with no problems.
