摘要： A single lens reflex camera has a finder optical system that observes an image formed on a reticle by an objective lens, and a photometric device that measures light transmitted through the reticle via at least a part of the finder optical system, at a position shifted from an optical axis of the finder optical system. The finder optical system comprises a Fresnel lens surface which transmits light from the objective lens, and the Fresnel lens surface is positioned so that the center of the Fresnel lens surface is shifted in a direction to cross the optical axis of the finder optical system according to a position of the photometric device.

摘要： An imaging lens SL mounted in a single lens reflex digital camera 1 is composed of, in order from an object side, a first lens group G1 having negative refractive power, a second lens group G2 having positive refractive power, and a third lens group G3 having negative refractive power. Upon focusing on a near-distance object from an infinitely distant object, a configuration is that at least any one of the first lens group G1 and the second lens group G2 is moved to the object side to vary a distance between the first lens group G1 and the second lens group G2. Accordingly, a downsized imaging lens having a small moving amount upon shooting a close range object, in which various aberrations are well corrected is provided.

摘要： An eyepiece lens includes first lens group G1 having a negative refracting power including a negative meniscus lens with a concave surface facing eyepoint E.P side, second lens group G2 having a positive refracting power including a lens with both convex surfaces on both ends, and third lens group G3 having a negative refracting power including a negative lens. The first—third lens groups are arranged in an order from eyepoint E.P side, and the eyepiece lens is capable of varying a diopter by moving the second lens group along an optical axis. The eyepiece lens is configured by aspherical surfaces to make the positive refracting power weak while at least one surface of the convex surfaces of the lens deviates from the optical axis. Further, conditions of a following formula are satisfied: 1.6

摘要： A real image viewfinder of an optical device includes an eye piece through which an optical axis may be viewed with respect to a target frame. The target frame may be used for centering an optical image on an image forming plane and also for autofocus of the optical device. The real image viewfinder includes a first prism for redefining an optical axis within the optical device. The first prism has a pair of reflective planes joined about a first ridge line. The first ridge line generally includes a number of manufacturing flaws which are noticeable by the photographer. Thus, viewfinder components are shifted by a predetermined amount to present the first ridge line in an area of the viewfinder which is different from the target frame as viewed through the eye piece. Likewise, the real image viewfinder includes a second prism having a second ridge line which is also shifted away from the target frame as viewed through the eye piece.
摘要翻译：光学装置的真实图像取景器包括眼镜片，通过该眼镜片可以相对于目标框架观察光轴。目标帧可以用于在图像形成平面上对准光学图像并且还用于光学装置的自动聚焦。真实图像取景器包括用于重新定义光学装置内的光轴的第一棱镜。第一棱镜具有围绕第一脊线连接的一对反射平面。第一脊线通常包括摄影师可以看到的许多制造缺陷。因此，取景器部件偏移预定量，以便在通过眼部件观察时在取景器的与目标框架不同的区域中呈现第一脊线。同样，真实图像取景器包括具有第二脊线的第二棱镜，该第二棱线也通过眼片观察而远离目标框架。
