Abstract
In an optical viewer instrument with a photographing function, a telescopic lens system is used for observing an object, and a digital camera is used for photographing an object. The digital camera includes a CCD image sensor and a photographing lens system associated with each other such that the object is formed as a photographic image on the sensor through the photographing lens system. An automatically-operable focussing mechanism is associated with the photographing lens system such that the object is brought into focus through the telescopic lens system, and such that the object is brought into focus through the photographing lens system. Optical various parameters are selected such that predetermined conditions are fulfilled, whereby the focussing of the photographing lens system can be suitably and properly performed in an automatic focussing manner.
