I just bought a Pocketwizard MiniTT1 and a FlexTT5. They look pretty awesome from what I have read and seen. I only had a little bit of time to try them out on my lunch break today but I had to give them a shot. A couple of questions....I tried using it in my studio and was hoping to use the 580EXII as a backlight and my strobe/softbox for my key. My strobe is triggered by any other flash so I thought this would work but it didn't seem to be working correctly. So I'm wondering if this has something to do with when it fires compared to the 580EXII? Is this adjustable in the utility? Another thing I wanted to try out was using the FlexTT5 to trigger my strobe. It's not a pocketwizard strobe, and from what I understand you can put it in "Basic Trigger Mode" to use with other cameras and devices. But it says not to enable this with a compatible Canon camera....which I do have. Is there a certain way I can use this to trigger my strobe?
