The invention relates to a microscope (10) having a movable stage (18) and an adjusting unit (24) for moving the stage (18). The adjusting unit (24) comprises a drive shaft (38) by the rotation of which the distance between the stage (18) and a base (22) of the microscope (10) is adjustable. Further, the microscope (10) has a manually operable operating unit (26) with a first output shaft (46) as well as an electric drive unit (28) for the motorized movement of the stage (18) with a second output shaft (52). In a manual operating mode, the drive shaft (38) is coupled to the first output shaft (46) via a first coupling unit (54), and in a motorized operating mode the drive shaft (38) is coupled to the second output shaft (52) via a second coupling unit (56).
