| 1. A drive controlling apparatus for controlling a drive of a plurality of optical adjusting members included in an optical
system of an optical apparatus, comprising:
a memory configured to store preset drive information of each of the optical adjusting members which include at least one
preset speed and at least one preset position;
a controller configured to control the drive of each of the optical adjusting members on the basis of the preset drive information,
including a state in which the plurality of the optical adjusting members are simultaneously driven; and
a selection member configured for a user to select a speed mode from a plurality of speed modes, each mode having set conditions
that correspond to the preset drive information,
wherein the controller sets a drive speeds for each optical adjusting member in accordance with the set conditions for the
selected mode; and
wherein one of the plurality of modes includes set conditions that set the drive speed of a first optical adjusting member
of the plurality of optical adjusting members to a preset speed and set the drive speed of a second optical adjusting member
to a speed calculated from the drive speed of the first optical adjusting member such that the drive of the first and second
optical adjusting members to the preset positions stored in the memory are substantially simultaneously completed.
