I have been using Canon 5d series for the last five or so years. As a "prosumer" style ff camera, they do not have a built in flash. As a consequence, electrical sync cords are a must. I am tired of spending $150+ for replacing these cords every other year or so, despite taking compulsive care of them. Does anyone know if there is a way of simulating on-camera flash from the hotshot to sync through a fiberoptic cable to Sea&Sea DS-1 flash.

There is a small led driven board that you can buy (works fine for 7D) check the flash forum.

I couldn't find what you were referring to, but doesn't the 7d use its popup flash to fire the strobes?

http://wetpixel.com/...showtopic=44632 for the micro strobe.
Yes the 7D has a popup flash but the LED uses no battery power and will shoot as fast as the strobe recycles.

The LED micro strobe didn't work for me with the 7D and the YS-D1, not enough Oomph to the LED. No problems though using the pop up flash. If you have Z240's I'd be happy to sell you mine =).

Thanks for the link, Bill. At least I know that it is feasible, if not commercial. In an email from Jean Bruneau at Aquatica, and on the Nauticam web site, both companies are looking at the feasibility of this concept.

At DEMA Nauticam had an LED based device that would work for the 5DIII (but not my 7D) that should be available by the end of the summer (maybe).

I can get my led micro to mostly work with the D1 if I fiddle around with the placement and I am using higher power (I think) LEDs from Unique-LEDs.
