ABSTRACT:
The object of this invention is to attain accurate control by correcting any deviation of a cam locus due to manufacturing errors and the like upon controlling a zoom lens and focus lens along a theoretical cam locus. To attain this object, a differential locus between the theoretical cam locus (stored cam locus) and a true cam locus due to an error obtained by a measurement is obtained, and is stored as cam correction data. The lens control is made while correcting the theoretical cam locus by the correction data.
