    • A taking lens apparatus has a zoom lens system that forms an optical image of an object at a variable magnification and that includes an aperture stop in the optical path, and an image sensor that has a light-receiving surface that converts the optical image into an electrical image signal and outputs it. The zoom lens system includes an optical member having a reflective surface that reflects a light beam in such a way that the optical axis is bent at substantially 90°. Moreover, prescribed conditions are fulfilled among the focal length of the entire zoom lens system at the wide-angle end, at the telephoto end, the axial distance from the image plane to the exit pupil at the wide-angle end, and the axial distance from the image-side surface of the most image-side lens element to the image plane.
    • 拍摄镜头装置具有变焦透镜系统,其以可变倍率形成物体的光学图像,并且在光路中包括孔径光阑,以及具有将光学图像转换成光学图像的受光面的图像传感器 电图像信号并输出​​。 变焦透镜系统包括具有反射表面的光学构件,该反射表面以使得光轴基本上为90°的方式弯曲的方式反射光束。 此外,在广角端,望远端,广角端处的从图像平面到出射光瞳的轴向距离和整个变焦透镜系统的焦距之间的规定条件,以及轴向距离 从最图像侧透镜元件的图像侧表面到图像平面。
