<p>PURPOSE:To simplify the association mechanism between the photography system and finder system and to vary the power of the finder system as well as the photography system by arranging a reflecting mirror so that the reflecting mirror can freely be extracted, moving a finder objective linearly at the time of varying power associatively with the movement of a photography system moving lens group, and arranging a light measuring means and a distance measuring means to part of the finder system. CONSTITUTION:The finder objective 8 is arranged in the optical path of reflection of a reflecting mirror 7 and moved linearly associatively with the power variation of the photography system to vary the finder power, and the other piece of luminous flux split by a half-mirror 9 is guided to the light measuring means through a visual field mask 17 serving as the light measuring means to measure the light and distance at the same time. The visual field mask 17 is composed of a thin film type light measuring sensor and serves as the light measuring means. Consequently, the device is reduced in size on the whole and a finder image which has no finder parallax can be observed.</p> |
