ABSTRACT:
A diopter control apparatus in a zoom camera having a variable finder optical system in which zooming is carried out by varying the distance between at least two lenses of the variable finder optical system. The diopter control apparatus includes a diopter correcting lens which constitutes a part of the variable finder optical system and which is supported for movement in the optical axis direction of the variable finder optical system. A motor is driven to move the lenses of the variable finder optical system in the optical axis direction in accordance with a switching operation to carry out zooming. A transmission mechanism transmits the rotation of the motor to the diopter correcting lens to move the latter in the optical axis direction, and a switching button selectively transmits the rotation of the transmission mechanism to an eyepiece which serves as the diopter correcting lens.
