Abstract: Three elongate, circular rods are secured to the inner peripheral surface of a lens barrel to extend axially thereof and in angularly spaced relation to each other. Each of two cylindrically shaped lens housings is mounted coaxially in the barrel for axial adjustment therein by means of three sets of rollers, each of which sets is mounted on the housing to have rolling, point engagement with a different one of the rails. At least one set of rollers on each housing is urged resiliently into rolling engagement with the associated rail, and each housing is connected to one of two camming rings which is rotatably mounted on the barrel to effect axial adjustment of the housings.

Abstract: This camera includes two kinds of photographing modes, a normal photographing mode and a trimming photographing mode of telephotographing in pseudo. The focal length variator for changing the focal length of a zoom lens is formed by a first cam corresponding to the normal photographing, a second cam corresponding to trimming photographing, and a transition area cam connecting the first cam and the second cam. Thus, at the time of transition from the normal photographing mode to the trimming photographing mode, or the transition from the trimming photographing mode to the normal photographing mode, the focal length of the zoom lens is changed to the focal length corresponding to the photographing mode by zooming operation to facilitate change of the photographing mode and always set a view finder to a suitable angle of view corresponding to the focal length set in the zoom lens.

Abstract: A first movable barrel is rotated and moved along an optical path by driving force of a motor. A second movable barrel is attached to the interior of the first movable barrel. The second movable barrel does not rotate, but goes straight along the optical path together with the first movable barrel. Inside the second movable barrel, is rotatably attached a lens turret in which a plurality of lenses are concentrically arranged. The lens turret is intermittently rotated in accordance with a rotation of the first movable barrel to set one of the lenses at the optical path. Each lens is set to the optical path at a position where back focus is taken into consideration, so that a focal length of a taking lens is changed. When the lens turret goes straight together with the second movable barrel without rotating, focusing is performed at the set focal length. A magnification of a viewfinder optical system is changed in association with a rotation of the lens turret.

Abstract: An exposure start determining section executes exposure start determination to reduce shaking during exposure, on the basis of the output of the shake detecting/computing section. At this time, an exposure start method used in the exposure start determining section is changed in accordance with a change condition set in a condition setting section. For example, in accordance with an exposure start instructing operation (a releasing operation), preparatory operations (such as a mirror-raising operation, a lens stop down operation, etc.) for exposure are executed. When the preparatory operations have finished, the shake detecting/computing section and the exposure start determining section start to operate. An exposure-start-determining-method changing section changes an exposure start determination method used in the exposure start determining means before and after a predetermined period elapses from the start of the shake detecting/computing section and the exposure start determining section.

Abstract: When a focused image tremble is within a correctable range of a correction lens which is included in a photographing optical system, the correction lens is driven following the focused image tremble. While the focused image tremble is out of the correctable range, the correction lens is driven to approach to a standard position, at which an optical axis of the correction lens is coaxial with an optical axis of other optical systems included in the photographing optical system, by a predetermined time constant. When a direction of the focused image tremble is reversed after the focused image tremble becomes beyond the correctable range, the focused image tremble is supposed to be displaced at a position corresponding to a position at which the correction lens would be situated at that time, and the driving of the correction lens is restarted.
