摘要

A binocular telescope with a photographing function includes a pair of telescopic optical systems, a casing for receiving the telescopic optical systems, and the casing has outer-side end portions. A camera system includes a photographing optical system, and a solid-state image sensor arranged behind and aligned with the photographing optical system, and an electronic control system electronically controls an operation of the camera system. The electronic control system is supplied with electric power from the batteries through an electric power source circuit board. The batteries and the electric power source circuit board are provided at the outer-side end portions of the casing, such that the weight is balanced between the outer-side end portions of the casing.
