Abstract
A lens apparatus includes a fixed member having one of a click generator and a groove part in which a groove part is formed, an operation ring having the other of the click generator and the groove part, and rotatable relative to the fixed member, a click detector configured to detect contact between the click generator and the groove part, and a rotation detector configured to detect rotation of the operation ring. The groove part has groove portions and non-groove portions alternately arranged. The click generator is biased along an optical axis direction and is in contact with the groove part. The click detector and the rotation detector are disposed along the optical axis direction.
Claims23
A lens apparatus comprising:
- a fixed member having one of a click generator and a groove part in which a groove part is formed;
- an operation ring having the other of the click generator and the groove part, and rotatable relative to the fixed member;
- a click detector configured to detect contact between the click generator and the groove part;
- and
- a rotation detector configured to detect rotation of the operation ring,
- wherein the groove part has groove portions and non-groove portions alternately arranged,
- wherein the click generator is biased along an optical axis direction and is in contact with the groove part, and
- wherein the click detector and the rotation detector are disposed along the optical axis direction.
An imaging apparatus comprising:
- a lens apparatus;
- and
- an image sensor configured to receive an image formed by the lens apparatus,
- wherein the lens apparatus includes:
- a fixed member having one of a click generator and a groove part in which a groove part is formed;
- an operation ring having the other of the click generator and the groove part, and rotatable relative to the fixed member;
- a click detector configured to detect contact between the click generator and the groove part;
- and
- a rotation detector configured to detect rotation of the operation ring,
- wherein the groove part has groove portions and non-groove portions alternately arranged,
- wherein the click generator is biased along an optical axis direction and is in contact with the groove part, and
- wherein the click detector and the rotation detector are disposed along the optical axis direction.
A lens system comprising:
- a fixed member having one of a click generator and a groove part in which a groove part is formed;
- an operation ring having the other of the click generator and the groove part, and rotatable relative to the fixed member;
- a rotation detector configured to detect rotation of the operation ring;
- and
- a controller configured to control a driven member driven based on a rotation operation of the operation ring,
- wherein the controller is configured to control the driven member based on an average rotational velocity of the operation ring obtained based on the detected rotation.
An imaging apparatus comprising:
- a lens apparatus;
- and
- an image sensor configured to receive an image formed by the lens apparatus,
- wherein the lens system includes:
- a fixed member having one of a click generator and a groove part in which a groove part is formed;
- an operation ring having the other of the click generator and the groove part, and rotatable relative to the fixed member;
- a rotation detector configured to detect rotation of the operation ring;
- and
- a controller configured to control a driven member driven based on a rotation operation of the operation ring,
- wherein the controller is configured to control the driven member based on an average rotational velocity of the operation ring obtained based on the detected rotation.
