Lens barrel, method of controlling lens barrel, camera body, method of controlling camera body, imaging device, and method of controlling imaging device

Abstract

There is provided a lens barrel that can easily and reliably prevent an erroneous operation at the time of switching of a manual focus mode. A lens barrel body houses an imaging optical system including a focus lens. A focus operation ring rotates integrally with a first connection ring about an optical axis of the imaging optical system. A second connection ring is movable between an engagement position at which the second connection ring is engaged with the first connection ring and a cam ring and a disengagement position at which the second connection ring is not engaged with both of the first connection ring and the cam ring. A switching-operation ring is movable between a rotation-restriction position at which the switching-operation ring moves the second connection ring to the engagement position and a rotation-allowable position at which the switching-operation ring moves the second connection ring to the disengagement position.
