PROBLEM TO BE SOLVED: To properly control the position of a moving member without providing a device with an expensive means detecting the position of the moving member by selectively energizing a stepping motor so that it is driven according to whether the moving member is set at a first position, a second position or another position when the moving member is moved. SOLUTION: When the power source switch 203 of a camera main body 200 is turned on and power is started to be supplied to a lens main body 300 from a power source, the stepping motor of a lock means 305d in a correction optical device 305 is energized so as to be driven at the interval of an energizing pulse T2(second driving pattern) by a lens CPU 301 and a lock ring is driven to a lock state. Next, when an SW-1 signal is generated at a release switch 204 and an IS action is selected, the stepping motor is energized so as to be driven at the interval of the energizing pulse T2(first driving pattern) by the CPU 301 so that the release of the lock means 305d is executed in order to realize a shake correction control action. Thus, the lock means 305d can be surely moved to the desired state. |
