摘要： A real image type zoom finder optical system is constructed by an objective optical system, an erect orthoscopic optical system and an eyepiece optical system sequentially arranged from an object side. The objective optical system is composed of first to fourth lens groups each constructed by a single lens. The erect orthoscopic image optical system is composed of two erect prisms. The eyepiece optical system is composed of one lens group. A front face of the second lens group is constructed by an aspherical surface such that the first, second, third and fourth lens groups respectively have positive, negative, positive and positive refracting powers. A real image formed by the objective optical system is focused and formed within the erect orthoscopic image optical system. A zooming operation is performed by moving the second lens group from the object side to an eyepiece side on an optical axis of the finder optical system. A change in diopter of a finder caused by this zooming operation is corrected by an axial movement of the fourth lens group.

The first lens provided at the optical deflector side is a positive meniscus lens with a concave surface facing toward the optical deflector side and has a co-axial aspherical shape at both sides. The second lens provided at the surface to be scanned side is symmetrical relative to an optical axis thereof and has a non-arc shape in the deflected plane at least at one surface, and the non-arc surface is shaped such that the radius of curvature in the sub scanning cross-section changes in the direction corresponding to the main scanning direction in a manner such that the curvature center line plotting the curvature center in the sub scanning cross-section of the lens surface in the direction corresponding to the main scanning direction is a curve different from the non-arc shape in the deflected plane.

摘要： A real image type zoom finder has a Porro prism for an erecting image arranged between an objective lens system and an eyepiece system, and a reflecting mirror or a movable prism constituting a portion of the Porro prism. The reflecting mirror or the movable prism is moved in a direction of an optical axis of the lens systems in accordance with distance information about a photographed object from a focal length detector, and/or information about the focal length of a zoom lens from a zoom focal length detector, thereby correcting parallax. The reflecting mirror may be composed of two overlapped mirrors constructed by a first mirror as a semi-transparent mirror arranged on the side of an objective lens and a second mirror composed of a total reflection mirror. In this case, the second mirror can be moved in the direction of the optical axis of the lens systems by a moving amount according to information about the focal length of the zoom lens.
