Hi,
I bought last year the Ikelite housing for a Canon EOS 40D with a DS 125. Unfortunately I have no many oppotunities to use it, so my confidence level is low. My problem is that the strobe seems to work in TTL mode, but I never get exposure time short enough to get not blurred pictures, working in Av or in Tv. This, of course, especially with a dark scene. In Av I set also the camera to 1/250 in Av or 1/125 in Tv, but also the lowest f-stops are not enogh to get a correct exposure from the camera. The camera fires the strobes but it seems to use the aperture and shutter as it hasn't. The green confidence signal of the strobes usually doesn't glow.
The housing is set to DS 125 and not to DS 51. In the camera I don't get the menu to change the external flash settings.
I use a Canon macro 60mm and a Tokina 10-17mm.
Are there any settings in the camera to choose or do you have any suggestions?
Thanks in advance for your help.
