Well, no, it's NOT instantaneous. On an RF camera, the only limiting factor between the decision by the photographer to shoot and the taking of the picture is the human slowness of responding physically to the decision: the actual mechanical release is a matter of 15 milliseconds or so from release of the shutter button to firing of the curtains. On an SLR, though, the mirror has to be flopped out of the way, and this delays things substantially. There is a fine article by the late Bob Schwalberg on this point -- it ran in Pop around 1989 or 1990. And Goldberg covers it in THE DARK SIDE OF THE LENS.
