Telescopic Sight

 

a viewfinder whose optical components form a telescopic (afocal) system.

In the USSR, telescopic systems consisting of a negative, or diverging, objective and a positive, or converging, eyepiece are found in cameras equipped with rangefinders and in some amateur motion-picture cameras. Such viewfinders are of small size and provide a reduced erect image of the object being photographed. They are known as direct-vision optical viewfinders.

Reflex cameras and professional motion-picture cameras employ a telescopic system with a positive objective and eyepiece. Systems of this type produce magnified images of the object being photographed but must be equipped with an inversion system in order to obtain an erect image.
