I'm got new Ikelite housing for CanonG9. But I have some problem about the sync cord connection. When the sync cord on the hotshoe is connected with the camera, the focus shown on the LCD is darkened. The camera also doesn't allow any adjustment on the flash mode. This problem happened to me once when I was using the camera on land. Back then, I fixed this problem by using flash. The amount of flash output was decreased to trick the camera. With this method, the picture shown on the LCD was back to normal. I'm afraid that this will be a problem for going for a night dive.
