ABSTRACT:
A camera, including an automatic lens focusing system of the type wherein a disc holding a plurality of different lens elements is accelerated by an arm of a torsion spring to effect disc rotation for sequentially presenting the lens elements at a focusing system, is provided with an arrangement for easily adjusting the amount of energy stored in the spring prior to release to thereby change the resultant disc rotational velocity. The adjustment is made in connection with a method of calibrating disc rotational velocity.
