Description

カメラに装着される交換レンズにおいて、交換レンズの初期化に関連した仕組みに関して、従来の技術とは異なる仕組みが望まれている。In an interchangeable lens attached to a camera, a mechanism different from the conventional technology is desired regarding a mechanism related to initialization of the interchangeable lens.

Claims

An interchangeable lens attached to the camera body,
A driven member whose position changes upon receiving a driving force;
An initialization unit that controls an initialization process for the driven member;
A first contact for transmitting position information regarding the position of the driven member driven by the driving force to the camera body;
A second contact different from the first contact for transmitting initialization information indicating the status of the initialization process of the driven member to the camera body;
Interchangeable lens.

An interchangeable lens attached to the camera body,
A driven member whose position changes upon receiving a driving force;
An initialization unit that controls an initialization process for the driven member;
A first transmitter that transmits position information regarding the position of the driven member to the camera body via a first transmission path;
A second transmitter for transmitting initialization information indicating the status of the initialization process of the driven member to the camera body via a second transmission path different from the first transmission path;
Interchangeable lens.

The interchangeable lens according to claim 2,
The initialization unit is an interchangeable lens that controls initialization processing for the driven member after initialization processing for the first transmission unit and the second transmission unit.

In an interchangeable lens having a driven member that changes its position upon receiving a driving force,
A process related to initialization is performed on the driven member,
Position information on the position of the driven member is transmitted to the camera body via the first contact;
An interchangeable lens that transmits initialization information indicating a status of processing related to the initialization of the driven member to the camera body via a second contact different from the first contact.

An interchangeable lens attached to the camera body,
A plurality of driven members whose positions are changed by receiving a driving force;
An initialization unit for controlling an initialization process for each of the plurality of driven members;
A first contact for transmitting position information related to a position of at least one driven member of the plurality of driven members to the camera body;
A second contact different from the first contact for transmitting initialization information individually indicating the status of the initialization process for each of the plurality of driven members to the camera body;
Interchangeable lens.

An interchangeable lens attached to the camera body,
A plurality of driven members whose positions are changed by receiving a driving force;
An initialization unit for controlling an initialization process for each of the plurality of driven members;
A first transmission unit configured to transmit position information regarding the position of at least one driven member among the plurality of driven members to the camera body via a first transmission path;
Second transmission for transmitting initialization information individually indicating the status of the initialization process for each of the plurality of driven members to the camera body via a second transmission path different from the first transmission path. And
Interchangeable lens.

The interchangeable lens according to claim 6,
The initialization unit is an interchangeable lens that controls initialization processing for the plurality of driven members after initialization processing for the first transmission unit and the second transmission unit.

In an interchangeable lens having a plurality of driven members whose positions change upon receiving a driving force,
A process related to initialization is performed on each of the plurality of driven members,
Transmitting positional information related to the position of at least one driven member of the plurality of driven members to the camera body via the first contact;
An interchangeable lens that transmits initialization information individually indicating a status of the processing related to the initialization for each of the plurality of driven members to the camera body via a second contact different from the first contact.

In the interchangeable lens as described in any one of Claims 5-7,
The initialization unit is an interchangeable lens that performs initialization processing of the plurality of driven members in parallel.

The interchangeable lens according to claim 8 or 9,
An interchangeable lens that starts executing initialization processing of the plurality of driven members simultaneously.

In the interchangeable lens according to any one of claims 5 to 10,
One of the plurality of driven members is a diaphragm,
An interchangeable lens that completes the aperture initialization process prior to the initialization process of other driven members.

The interchangeable lens according to claim 11,
An interchangeable lens that transmits the initialization information indicating that initialization processing of driven members other than the aperture is not completed until the aperture initialization processing is completed.

In the interchangeable lens as described in any one of Claims 5-7,
The initialization unit is an interchangeable lens that performs initialization processing of the plurality of driven members one by one in a predetermined order.

In the interchangeable lens according to any one of claims 1 to 13,
An interchangeable lens that transmits the position information to the camera body at a first predetermined cycle and transmits the initialization information to the camera body at a second predetermined cycle different from the first predetermined cycle.

The interchangeable lens according to claim 14,
The first predetermined period is an interchangeable lens that is faster than the second predetermined period.

An attachment portion to which an interchangeable lens having a plurality of driven members whose driven positions change by receiving a driving force is detachably attached;
A first receiver that receives position information about the position of at least one driven member of the plurality of driven members from the interchangeable lens via a first contact;
Initialization information indicating the status of initialization processing performed by the interchangeable lens for each of the plurality of driven members for each of the driven members is transmitted via the second contact different from the first contact. A second receiving unit for receiving from,
Camera body with

The camera body according to claim 16, wherein
A control unit for executing a predetermined control process on each of the plurality of driven members;
The control unit is a camera body that cannot execute the control process on a driven member that is indicated by the initialization information that the execution of the initialization process is incomplete.

The camera body according to claim 17,
One of the plurality of driven members is a diaphragm,
The control unit is a camera body that causes the diaphragm to perform an aperture control process that is the predetermined control process.

The camera body according to any one of claims 16 to 18,
Receiving the position information from the interchangeable lens every first predetermined period;
A camera body that receives the initialization information from the interchangeable lens at a second predetermined period different from the first predetermined period.

The camera body according to claim 19,
The first predetermined cycle is a camera body that is faster than the second predetermined cycle.
