No sync

Hi

I have a question regarding my canon 5D(in a subal housing CD5) and a Ikelite DS51

when I use the Av mode(aperture-priority) on my canon camera and set my DS51 into F position the shutter time will be fixed at 1/200, if I shut off the strobe the shutter time will start to change as it is supposed to do. Does anyone recognize this problem? I don't use any TTL at all. I use #4104.6 sync cable,

The problem is solved, I cut the green cable in the Subal Housing

You cut the green cable! You were supposed to cut the red cable - now the bomb is going to explode for sure! Just kidding - sorry I watch too many movies :-)

I recommend you look at the custom functions in your 5D. You can set the flash sync to be either default to 1/200th when a flash is connected, or to float from 1/200th down to whatever the meter tells the camera to set the shutter speed.

What you do not want to happen is for the SS to go above 1/250th or so - if you do, you'll start to see a black line across the bottom of the photo. I know because it's happened to me when I cut all the wires except for the Fire and Ground. I have a Subla housing too btw, but use it w/ all 6 wires and a Sea and Sea ttl converter.
