I just received a pair of them today and tested them. No miss fire, however, I have a question.
If you're using ETTL on Av mode, no way to sync up > 1/200s ? Sorry, I am really new to flash light world.

BrandonSi Nevermind.. I'm silly.  More info | Mar 28, 2011 21:39 | #2 Flash fact #6*: Every SLR camera with a mechanical shutter has a maximum flash sync shutter speed (1/200 or 1/250 on current Canon DSLRs). This has to do with the way focal plane shutters work. At slower shutter speeds, the first curtain opens, the flash fires, and after the specified time duration, the second curtain closes behind it. At shutter speeds faster than flash sync, the second curtain begins to close before the first curtain is completely open. The second curtain follows the first across the frame, exposing only a slice of the image at any given moment. Firing a flash during this process would illuminate only part of the image. You may find the entire Flash 101 post worth reviewing, there is some good information there if you're just getting started.

The Pixel triggers can do HSS, so you can sync to whatever your max is (1/8000s or 1/4000s depending on which camera you use). If you have a specific shutter speed in mind then set the camera to M and set it. When you're in Av the camera sets the SS. gordon
