Follow focus

Abstract

A follow focus for cameras, in particular film cameras, comprising a bevel gear having a first rotary axis (11) and a second rotary axis (13) arranged at an angle, in particular a right angle, to one another, a first transmission mechanism (26, 27) for transmitting the rotation of one of the axes (11) onto the other axis (13) by means of a positive locking connection acting in the direction of rotation of the axes, and a second transmission mechanism (28, 30) for transmitting the rotation of one of the axes (11) onto the other axis (13) by means of a frictional connection acting in the direction of rotation of the axes, wherein the rotation of the one axis (11) can be transmitted to the other axis (13) by means of the frictional connection of the second transmission mechanism (28, 30) until the frictional connection of the second transmission mechanism (28, 30) is overpowered and after the frictional connection has been overpowered it can be transmitted primarily by the positive locking connection of the first transmission mechanism (26, 27).
