Mirror lock

An extra feature found on only a few cameras that is used to lock the viewing mirror in the up position while the shutter is fired. The benefit is almost no vibration as well as the ability to keep up with an ultra-fast motor drive. This feature tends to be more common on medium format cameras because the mirror is larger and creates more vibration as it bounces out of the way of the film plane.
