You may find it useful to mute the shutter at stage performances, during interviews, or for wildlife photography.
When quiet shutter-release mode is selected in viewfinder photography, the mirror stays up while the shutter-release button is pressed all the way down. The mirror is lowered (more quietly than in single-frame mode) only when the shutter-release button returns to the halfway position, allowing you to control the timing of the click made by the mirror. In live view, the sound of the mirror being raised is eliminated altogether.
To choose quiet shutter-release mode, press the release mode dial lock release and rotate the dial to Q.
You can also achieve the effect of silent photography by filming movies silently and then later playing the movie back and using the Save selected frame option to create JPEG stills from selected frames.
