Just to add some more confusion/data to the situation:
I've been attempting to do this in S mode with the shutter set to 1/125.
When I hit the "test fire" button on the transmitter, the light on the receiver comes on (and off, just as one would expect).
Also, I have a SIGMA EF-530 DG Super which is behaving the same way.
This may seem an oddball question... but which firmware version do you have installed on your camera?
