I know the topic of converting an ikelite housing from the 5d to 5d mark ii has been discussed at length. However, I am unable to get my ds125 to fire using the Mark ii in the original 5d housing. Does anybody know why this is? The TTL light lights up on the housing but no matter what setting I put the strobe on, it will not fire. The hot shoe mount seems to fit fine but I have no idea what the issue is. Any help would be much appreciated.
