Patent ID: 8744257

Claim:
A lens apparatus comprising: an optical member; a driving unit that drives the optical member; a position detector that detects a position of the optical member; an operation portion configured to rotate toward a first direction and a second direction opposite to the first direction; a rotation portion configured to rotate interlockingly with an operation of the operation portion; a rotation detector that detects a rotation amount of the operation portion; a driving controller configured to control the driving unit to drive the optical member based on the rotation amount of the operation portion detected by the rotation detector, the driving controller driving the optical member toward a first end upon the operation portion being rotated in the first direction and driving the optical member toward a second end upon the operation portion being rotated in the second direction; a first regulator disposed on a side of the first direction of the rotation portion, the first regulator rotating in the first direction while abutting to the rotation portion during the rotation of the rotation portion in the first direction; a second regulator disposed on a side of the second direction of the rotation portion, the second regulator rotating in the second direction while abutting to the rotation portion during the rotation of the rotation portion in the second direction; and a lock controller configured to control the first and second regulators based on the position of the optical member detected by the position detector to lock the first regulator upon the optical member reaching the first end and lock the second regulator upon the optical member reaching the second end.
