An optical apparatus ensuring smooth driving control of an optical member is disclosed. The optical apparatus includes an optical member, a stepping motor configured to drive the optical member, a driving commander configured to generate driving pulses supplied to the stepping motor, a pulse count generator configured to count the driving pulses output from the driving commander, a position detector configured to detect a position of the optical member, and a pulse count presetter configured to replace, based on an output of the pulse count presetter and an output of the position detector, a pulse count output from the pulse count presetter with a pulse count corresponding to the output of the position detector. |
