摘要： A light-quantity adjusting apparatus is disclosed, in which a light-blocking member and an optical filter can be driven with a single actuator, and which can be made compact. The light-quantity adjusting apparatus includes a light-blocking member that changes a quantity of light through an open/close operation within an optical path, an optical filter that can be inserted into and withdrawn from the optical path, independently from the light-blocking member, and a driving mechanism that has a single actuator as a driving source and that drives the light-blocking member and the optical filter. The driving mechanism drives the optical filter by operating the actuator further in an opening direction after the actuator has driven the light-blocking member into an open position, and operating the actuator further in a closing direction after the actuator has driven the light-blocking member into a closed position.
