Are there any known issues with using a Yongnuo RF603N II with a Nikon D5100? I am trying to trigger a Yongnuo 560 III with the RF603N II. When I mount the 560 III directly on the D5100, it triggers from releasing the shutter.
But when I have the RF603 mounted on the D5100 releasing the shutter will not trigger the 603 through the hotshoe, but when I use the test button on the RF603 mounted on the D5100 it triggers the flash remotely. For some reason it seems like my camera is not triggering the transmitting 603 through the hotshoe. Am I missing something here?
