    • A photographic optical system (1) is described having a cam ring (14) with at least one groove (20, 21) therein, said cam ring (14) being rotatable at a constant axial position, and said system (1) further having at least one movable lens barrel (22, 23, 24, 25, L1) movable along an optical axis of said photographic system (1) in association with rotation of said cam ring (14). Said system (1) having at least one light intercepting member (210, 220) positioned about the periphery of said cam ring (14), said member (210, 220) thereby comprising means (211, 90) for covering each said camming groove (20, 21) and for preventing light from entering the interior of said cam ring (14). In an embodyment of the Invention at least one light intercepting member (220) is positioned in a space (W) between a front end of a cam ring support (13) and there is a front cover (200) having an opening (201) through which said lens barrel (22, 23, 24, 25, L1) is adapted to move. In a further embodyment of the invention said light intercepting member (210) comprises a flexible code plate (90) wrapped about one peripheral portion of said cam ring (14), a light intercepting tape (211) positioned about a second peripheral portion of said cam ring (14), and an annular gear (15) positioned about a third peripheral portion of said cam ring (14). A camera comprising such a photographic optical system (1) is described, which is in one embodyment of the invention automatically focussed in accordance with the distance of a subject from a film plane in said camera.

    • A digital photographing device and a control method thereof for obtaining the image of a stable structure are provided to obtain the image arranged within the desired structure by equipping a motion sensor sensing the motion of a subject. A composition setup signal is received(S10). The subject is photographed and the video signal is generated(S11-S13). The corresponding image in the video signal is positioned within structure(S14). If the image is not positioned within structure, notify signal is generated(S15). If the image is positioned within structure, the release signal is generated. The movement of the subject is sensed. The mobile subject is photographed and the video signal is generated.

    • PURPOSE: A super wide angle variable power finder is provided to obtain a visual field at a super wide angle position of over 71 degrees, while substantially obviating the problems of the prior art, and have a good overall aberration performance from the wide angle position to a telephoto position in a real image variable finder optical system of either a lens shutter camera or a video camera. CONSTITUTION: An objective lens group(I) has an overall positive refractive power, and comprises first to fourth lens units(1-4). The first lens unit(1) remains fixed in position and has a negative refractive power with respect to an object. The movable second lens unit(2) is convex with respect to tee object and has a negative refractive power. The movable third lens unit(3) has a positive refractive power. The fourth lens unit(4) remains fixed in position and has a positive refractive power. In an eyepiece group(II) having a positive refractive power, the magnification of the object is changed by moving the third lens unit, a change in a view angle is compensated for by moving the second lens unit, and the following condition is satisfied: 1.75
