Interchangeable lens and camera body
An interchangeable lens mountable to a camera body includes a zoom lens configured to adjust an angle of view of a subject image, a driver configured to move the zoom lens in an optical axis direction, a plurality of operating members configured to generate an operation signal for driving the driver according to operation performed by a user, a communication unit configured to receive, from the camera body, setting information for setting valid/invalid of at least one of the plurality of operating members, and a controller configured to control the driver. The controller drives and does not drive the driver based on the operation signal from the operating member having been set to valid and invalid, respectively, by the setting information received through the communication unit.
1. An interchangeable lens mountable to a camera body, comprising:
a zoom lens configured to adjust an angle of view of a subject image;
a driver configured to move the zoom lens in an optical axis direction;
a first operating member configured to generate an operation signal used to drive the driver according to an operation performed by a user;
a second operating member configured to generate an operation signal used to drive the driver according to an operation performed by the user;
a communication unit configured to receive, from the camera body, setting information for setting at least one of the first and second operating members in a valid state or an invalid state; and
a controller configured to control the driver, wherein:
the controller:
sets at least one of the first and second operating members in the invalid state or the valid state based on the setting information received by the communication unit,
drives the driver based on the operation signal generated from the operating member having been set to the valid state or having not been set to the invalid state, and
does not drive the driver based on the operation signal generated from the operating member having been set to the invalid state.
2. The interchangeable lens according to claim 1 , wherein when the operating member having been set to the invalid state by the setting information is operated by the user and an operation time or an amount of the operation by the user exceeds a predetermined value, the controller drives the driver based on the operation signal generated from the operating member having been set to the invalid state.
3. The interchangeable lens according to claim 1 , wherein when the communication unit receives the operation signal for driving the driver from the camera body, the controller controls the driver based on the operation signal received from the camera body.
4. A camera body to which an interchangeable lens is mountable, the interchangeable lens including a first operating member configured to drive a zoom lens and a second operating member configured to drive the zoom lens, the camera body comprising:
an imaging unit configured to capture a subject image inputted through the interchangeable lens to generate image data;
a setting unit configured to set setting information for setting at least one of the first and second operating members of the interchangeable lens in a valid state or an invalid state; and
a communication unit configured to send the setting information to the interchangeable lens.
5. The camera body according to claim 4 , further comprising a camera body operating member configured to accept an operation from a user, wherein
the setting unit sets the setting information based on the operation of the camera body operating member by the user.
6. The camera body according to claim 4 , wherein the setting unit sets the setting information according to an operating state of the camera body.
7. The camera body according to claim 6 , wherein
one of the first and second operating members of the interchangeable lens is a zoom ring configured to generate an operation signal used to drive the zoom lens according to a rotation operation, and
the setting unit sets the zoom ring to the invalid state when the operating state of the camera body is a moving image shooting state.
8. The camera body according to claim 4 , further comprising a sensor configured to detect an orientation of the camera body, wherein
the setting unit sets the setting information according to the orientation of the camera body detected by the sensor.
9. The camera body according to claim 4 , further comprising a camera body operating member configured to generate an operation signal used to drive the zoom lens based on an operation performed by a user, wherein
the communication unit sends the operation signal generated by the camera body operating member to the interchangeable lens.
10. The camera body according to claim 4 , further comprising:
a display unit configured to display predetermined information; and
a controller configured to control the display unit, wherein
when the communication unit receives, from the interchangeable lens, information about an operation performed by a user on the operating member having been set to the invalid state by the setting information, the controller allows the display unit to display information indicating that the operating member operated by the user is set to the invalid state.
11. The camera body according to claim 10 , wherein when information about an operation performed by the user on the operating member having been set to the invalid state by the setting information is received from the interchangeable lens, the display unit displays information indicating that the operating member operated by the user is set to the invalid state only if an operation time or an amount of the operation by the user exceeds a predetermined value.
12. An interchangeable lens mountable to a camera body, comprising:
a lens disposed along an optical axis;
a driver configured to move the lens in a direction along the optical axis;
a first operating member configured to generate an operation signal used to drive the driver according to an operation performed by a user;
a second operating member configured to generate an operation signal used to drive the driver according to an operation performed by the user;
a communication unit configured to receive, from the camera body, setting information for setting at least one of the first and second operating members in a valid state or an invalid state; and
a controller configured to drive the driver in response to the operation signal generated by the operating member having been set in the valid state or having not been set in the invalid state, and to not drive the driver in response to the operation signal generated by the operating member having been set in the invalid state.
13. The interchangeable lens according to claim 12 , wherein one of the first and second operating members is a ring configured to be rotated by the user and the other of the first and second operating members is a switch configured to be switched to plural positions by the user.
14. The interchangeable lens according to claim 12 , wherein the lens is a focus lens or a zoom lens.
