In your initial post you also mentioned the 6.5 frames per second any external strobe will not be able to keep up with this rate. The eTTL exposure control actually errors (over exposes) if there is not enought time between shots.

Richard,

Thanks for sharing the info about the over exposure with continuous shooting with the strobes. That is very interesting. I pretty much chalked up the fact that I would not be able to get the 6.5 fps any where under water. In fact the 40D can not achieve this with normal flash.

It still is a great feature that comes in handy at the Red Sox games

. It also allowed me to get some great in-flight shots of a humming bird this past November while I was in Antigua. I was really impressed, especially since I got the camera only two days before the trip. It is very user friendly.

Just one question you raised that I was wondering if you could answer....what is the "down time" between your shots with your EOS Rebel set up with the ikelite system while being able to maintain some quality control on your exposure?

thanks in advance,

Tom
