A stereoscopic lens system for a stereo endoscope is disclosed, the stereoscopic lens system converting light propagated from an object and received at an objective end of the stereoscopic lens system to left and right optical images at an image plane end of the stereoscopic lens system. The system includes at least one linearly movable left optical element configured to selectably adjust the magnification and field of view of the left image in response to linear movement and at least one linearly movable right optical element configured to selectably adjust the magnification and field of view of the right image in response to linear movement. The at least one linearly movable left optical element and the at least one linearly movable right optical element are selectably movable in fixed relation to each other.
