Received 2 pcs of R1 last week. During yesterdays sport event, one of them ignored the precapture function and directly releases the shutter with half pressed button from one second to the other. No matter precapture is activated or not. This accures horizontal and vertical. Only solution so far, is to switch of the vertical ON/OFF, to make horizontal work properly. Copy the settings from the working one did not help either. Informed Canon today, waiting for an answer now. Anyone experienced the same behavior?
