| 摘要 |
An optical apparatus is disclosed, which comprises a detecting unit which detects a vibration to output a vibration signal, an amplifying circuit which amplifies the vibration signal and has a changeable amplification factor, a driving member which drives a lens unit, and a changing circuit which changes the amplification factor depending on whether or not the lens unit is driven by the driving member, thereby making it possible to output a relatively stable vibration signal even when a disturbance vibration occurs.
