Trouble with 7d, 580ex II, Lumopro LP160 combination
Jan 15, 2011

I just received a Lumopro LP160, purchased at the recommendation of the Strobist Blog. I'm planning to use it as a second slave. My 580ex II is my other slave. The 580 would be triggered by the 7D wireless. The Lumopro triggered optically by the camera flash, or the 580 flash.

The combination works fine with ETTL (there's a special setting on the Lumopro which ignores the pre-flash). However, when trying this manually, I can't make it work. Not when triggered by the on-camera flash or by the 580.

It's not that the lumopro is firing early. It's not firing at all.

Does anyone know the proper way to configure this? I've searched far and wide for the answer.

Or do I need to return the Lumopro?
Thanks so much for your help.
