The purpose of the Leica motorfocus system is to provide motordriven coarse and fine focusing by means of a manual control, a footswitch, or through a computer. Five exact focus settings can be stored.

Because of its modular design, the motorfocus system easily integrates with the incident-and transmitted-light stands of the Leica M125, M165 C, M205 A, M205 C, M165 FC and M205 FA stereomicroscopes.
