PURPOSE:To realize a camera device incorporating a stroboscope in which the electronic control is facilitated without causing the deterioration of performance, by securing the free detachment of a liquid crystal aperture plate form an optical system. CONSTITUTION:A switch lever 11 is connected to a power supply switch 12, and the power is supplied to a discharge tube 15 for the photography using an electronic flash. Thus a liquid crystal aperture plate 1 which is hooked by the tip part of the lever 11 and a wedge groove 18 moves to the 2nd position by the force of a spring 22. As a result, the plate 1 is detached from the photographing optical system, and no effect of transmittance is caused from the picture-taking lens system via the plate 1. Thus a reduction of the focal distance is prevented in the electronic flash photography to increase the distance of a subject by which a proper exposure is obtained. Thus a camera device incorporating stroboscope which has an easy and assured electronic control with no deterioration of performance secured without increasing the size of the camera body. |
