Lens barrel and optical apparatus having the same
摘要：
A lens barrel comprises a vibration detecting device for detecting a vibration, a correcting optical device for correcting the vibration on the basis of an output of the vibration detecting device, and a diaphragm unit having a variable aperture diameter, and the vibration detecting device is disposed in a plane which is approximately flush with a driving part for the diaphragm unit and perpendicular to an optical axis, or the vibration detecting device is formed on or integrally with a lens barrel portion which holds an optical member other than the correcting optical device.
