I have been bought the Canon RC-6 remote controller but is it correct that it only works when the camera is set on a timer delay exposure? I have tried it on my 60D and on both zero and 2 second timer settings there is a noticeable delay before the shutter fires. I understood that it could be operated on an "immediate" shutter setting to fire instantly when the remote button is pressed. I wanted this controller to enable me to capture wild birds or animals feeding but if there is always going to be a delay it won't be much good! Is this all correct or am I missing something?
