Abstract

PURPOSE:To make a video camera small-sized and light, and to improve its stability when photographing, by shortening the length in the transverse direction (depth direction) of the whole video camera, and removing a dead space. CONSTITUTION:A part of luminous flux from an object to be photographed, which has passed through a pre-group 1 of a photographing optical system is reflected downward by a semitransmissive reflection surface 2a of an optical splitter 2, and its image is formed on an image pickup surface 4a of an image pickup tube 4 through a post-group 3 of the photographing optical system. On the other hand, a luminous flux which has passed through the semitransmissive reflection surface 2a of the optical splitter 2 is offered for observation by a finder optical system 5. In this way, a small and light video camera can be constituted, and when the post-group 3 of the photographing optical system, the image pickup tube 4, etc. are provided in the grip, a dead space is removed and a smaller and lighter video camera is obtained.
