    • A camera having, in addition to a real focal length photographing mode, a pseudo focal length photographing mode, namely, a photographing mode in which a part of a photographed image frame of a film is printed at an enlarging ratio different from an ordinary enlarging ratio to obtain a print as if it had been photographed using a telephoto lens. It is provided with means for recording photographing mode information on a frame of a film when the pseudo focal length photographing mode is selected, and a control means which brings a flash light emitting device into an operable condition in response to the selection of the pseudo focal length photographing mode and which actuates the flash light emitting device in synchronism with release of the shutter. An optical axis of a photographing lens and a flash emission tube are spaced from each other, and the pseudo focal length photographing mode can be selected only when a negative film is loaded in the camera.
    • 除了实际焦距拍摄模式之外,相机还具有伪焦距拍摄模式,即,以与普通放大率不同的放大率打印胶片的拍摄图像帧的一部分的拍摄模式 以获得打印,好像它是用长焦镜头拍摄的。 具有当选择伪焦距拍摄模式时在胶片的帧上记录拍摄模式信息的装置,以及响应于伪焦点的选择使闪光灯发光装置进入可操作状态的控制装置 并且其与快门的释放同步地驱动闪光灯发光装置。 拍摄镜头和闪光发射管的光轴彼此间隔开,并且只有当相机中装载负片时才能选择伪焦距拍摄模式。

    • The present invention provides a front conversion lens system attachable in front of an objective lens of a camera in which either of a real focal length photographing mode and a pseudo focal length photographing mode in which, an area, in an image recorded in a frame, smaller than a normal printing area printed when selecting the real focal length photographing mode is printed, is selectable, the lens system satisfying the following condition:0.25 (f/ DF) (L-L')/L 7.0wherein; f represents a focal length of a photographing lens system including the front conversion lens system and the objective lens; DF represents an axial thickness of the front conversion lens system; L represents a length of a diagonal line of an image plane to be printed when the real focal length photographing mode is selected; and L' represents a length of a diagonal line of an image plane to be printed when the pseudo focal length photographing mode is selected.
    • 本发明提供了一种可附接在相机物镜前方的前转换透镜系统,其中实焦距拍摄模式和伪焦距拍摄模式中的任一种,其中,记录在帧中的图像中的区域, 小于正在打印的真实焦距拍摄模式下打印的正常打印区域,可以选择满足以下条件的透镜系统:0.25(f / DF)(L-L')/ L 7.0其中; f表示包括前转换透镜系统和物镜的拍摄镜头系统的焦距; DF表示前转换透镜系统的轴向厚度; L表示当选择实际焦距拍摄模式时要打印的图像平面的对角线的长度; 并且L'表示当选择伪焦距拍摄模式时要打印的图像平面的对角线的长度。
