摘要： A camera having an apparatus for adjusting a back focus by varying a distance between a rearmost point of lens groups of a photographing optical system and focal plane. The apparatus includes a stationary barrel that supports the lens groups and is fixed to the camera body, and a restricting mechanism that is provided between the camera body and the stationary barrel. The restricting mechanism restricts rotational movement of the stationary barrel with respect to the camera body, while allowing movement of the stationary barrel in an optical axis direction with respect to the camera body.

摘要： A camera having a zoom lens barrel that includes an aperture size changing mechanism including a pair of light intercepting members which are inserted into a retracted from a rectangular-shaped photographing aperture of the camera for changing the photographing aperture size. The camera further includes a non-rotational cylinder which moves in the direction of the optical axis of the zoom lens without rotating. A rotational cylinder is also included and is driven to rotate with respect to the non-rotational cylinder about the optical axis. A gear supporting member is supported on the non-rotational cylinder. The gear supporting member includes a raised portion projecting toward the photographing aperture. The camera further includes a gear train which is supported on the gear supporting member for transmitting a drive force to the rotational cylinder. At least a part of the gear train is supported by the raised portion, which is formed such that the orthographic projection thereof may not overlap the pair of light intercepting members in the optical axis direction.
