Abstract
A zoom stereomicroscope with taking lens barrel comprises a binocular observation stereomicroscope, formed by a pair of observation optical subsystems, and an auxiliary optical subsystem which may be used for purpose of photographing or auxiliary observation. The auxiliary subsystem is focussed in the same manner as the observation subsystems. Each optical subsystem includes a zooming movable lens. The movable lenses are connected with associated drive members which are driven in unitary fashion to change the magnification in the respective subsystems simultaneously.
