Optical driver apparatus, optical apparatus and image capturing apparatus

An optical apparatus comprising:

• a lens operation member operable manually;
• and
• a locking mechanism switchable between a locking state of restraining motion of the lens operation member and an unlocking state of releasing the restraint,
• wherein:
• the optical apparatus is configured such that an optical driving apparatus is detachably attachable thereto;
• and
• the optical driving apparatus comprises:
• a driving operation member;
• an actuator configured to move the lens operation member;
• and
• a controller configured to control the actuator,
• wherein the locking mechanism includes a first portion and a second portion,
• wherein the first portion engages with the second portion in the locking state and the first portion separates from the second portion in the unlocking state, and
• wherein the controller is configured to:
• drive the actuator in response to an operation of the driving operation member when the locking mechanism is in the unlocking state;
• and
• control the actuator, when the locking mechanism is in the locking state, so as to provide one of a state of not driving the actuator in response to the operation of the driving operation member and a state of performing a warning operation.

An image capturing apparatus that includes an image sensor and to which an optical apparatus as a lens apparatus is detachably attachable,

• wherein the optical apparatus comprises:
• an image capturing optical system;
• a lens operation member operable manually;
• and
• a locking mechanism switchable between a locking state of restraining motion of the lens operation member and an unlocking state of releasing the restraint,
• wherein the optical apparatus is configured such that an optical driving apparatus is detachably attachable thereto;
• wherein the optical driving apparatus comprises:
• a driving operation member;
• an actuator configured to move the lens operation member;
• and
• a controller configured to control the actuator,
• wherein the locking mechanism includes a first portion and a second portion,
• wherein the first portion engages with the second portion in the locking state and the first portion separates from the second portion in the unlocking state,
• wherein the controller is configured to:
• drive the actuator in response to an operation of the driving operation member when the locking mechanism is in the unlocking state, and
• control the actuator, when the locking mechanism is in the locking state, so as to provide one of a state of not driving the actuator in response to the operation of the driving operation member and a state of performing a warning operation;
• and
• wherein:
• the optical apparatus is configured to send, when the locking mechanism is in the locking state, warning information to the image capturing apparatus in response to the operation of the driving operation member;
• and
• the image capturing apparatus is configured to perform a warning operation in response to receipt of the warning information.
