Abstract
In an optical viewer instrument with a photographing function, there is provided a telescopic lens system for observing objects, and a digital camera system including a solid-state image sensor and a photographing lens system associated with each other such that an object is formed as a photographed image on the solid-state image sensor through the photographing lens system. A manually-operable focussing mechanism is associated with the telescopic lens system and 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 parameters are selected such that predetermined conditions are fulfilled, whereby the focussing of the telescopic lens system and the focusing of the photographing lens system can be suitably and properly performed by the focussing mechanism.
