Abstract
Optical equipment which can prevent image blurring and enable a lens to be stopped in a position requiring low power consumption is provided. The optical equipment includes a lens driver supplied with electric power from a camera body to drive a focusing lens. The equipment further includes an aperture driver that drives an aperture and a drive controller that positions the focusing lens to minimize power consumption and controls the aperture driver during opening of the aperture so that the focal position of the focusing lens falls within a focal depth. In this way, a lens position-controller that controls an AF motor can stop the lens in a position that does not cause image blur and reduces power consumption.
