Hi...a client of mine has a Canon G12 with and Ikelite Housing and dual D125 Strobes. The strobes seem to function normally at 1/8 and 1/4 power...but as soon as they are turned up to 1/2 or full power the shots come out almost black. This occurs whether on manual or automatic settings. I spent hours trying to trouble shoot this yesterday with no luck and am starting to think it might be the circuit in the hot shoe. The strobes and sync cord function perfectly when attached to his Sony compact camera. Any thoughts or ideas...something I am missing? Thanks for any help!
