Hi,
I use the MK-RC7 on a Canon 7D and a 40D. Have the same problem with both of them:
When I push the expo button on the camera body first time it doesn't trigger the flash. If I push it again it does it. I tried to shoot in continous mode and again the first didn't, all of the following shots were triggered. But after I waited 10-15 seconds the problem was same. When I push the test button on the trigger it always works. When I push the test then release the shutter button it works. But when I push the shutter button first and only one time it doesn't work. What could be the problem?
