Abstract
A camera includes a lens, and aperture blades. The aperture blades are movable between a minimum aperture position at which the aperture blades generate vignetting at a periphery of the photographing area and a maximum aperture position radially outward from the minimum aperture position. The camera further includes a switch including an operation lever movable through a user operation and an actuation lever connected to the aperture blades and operable to move the aperture blades between the minimum aperture position and the maximum aperture position in response to movement of the operation lever. The operation lever is movable in a circumferential direction about an optical axis. The actuation lever is rotatable about an axis. The operation lever has a cam slot elongated in the circumferential direction between an inner portion and an outer portion. The actuation lever includes a follower engageable with and movable along the cam slot.
