When shooting on the Sports mode with my camera, I can just hold down the Shutter Release button and it will continue to take pictures in succession. I've recently been trying to take my action shots in the Manual mode to control the lighting better, but I find that I can not hold the Shutter Release button down and have it keep taking photos. I have to keep pressing it as fast as I can. Is there a setting that will allow the rapid fire shooting while in Manual mode?
