Abstract
A single lens reflex camera which has improved high-speed photography operation. The mirror in the single lens reflex camera is controlled to reduce the time delay between a first time when the rear shutter blind closes the photo field and a second time when the mirror reaches the down position. The time delay is reduced by initiating the mirror down movement at least before the rear shutter blind closes the photo field and possibly before the front shutter blind even opens the photo field, depending on the exposure conditions.
