Abstract
A camera system having a camera body and an interchangeable lens is made more convenient to use. A camera system 1 includes an interchangeable lens unit 2 and a camera body 3. A body microcomputer 10 of the camera body 3 decides whether or not the interchangeable lens unit 2 is compatible with moving picture mode on the basis of lens information about the interchangeable lens unit 2. If the interchangeable lens unit 2 is not compatible with moving picture mode, the body microcomputer 10 prevents the operation of an imaging sensor 11 from being set to moving picture mode.
Claims8
A camera system, comprising:
- an interchangeable lens unit having an imaging optical system configured to form an optical image of a subject, a focus adjuster configured to optically adjust the focus state of the optical image, and a lens controller configured to control the operation of the focus adjuster;
- and
- a camera body having an imaging unit configured to convert the optical image of the subject into an image signal and configured to acquire an image of the subject, a focus detector configured to detect the focus state of the optical image by contrast detection method on the basis of the image signal, and a body controller configured to control the operation of the imaging unit and with which information can be exchanged with the lens controller,
- wherein the lens controller has lens information related to the interchangeable lens unit,
- the lens information includes information on whether or not a method for driving the focus adjustment of the interchangeable lens unit is compatible with wobbling,
- the body controller, based on the lens information, is configured to decide whether or not the interchangeable lens unit is compatible with wobbling, so that a focusing performance can be set based on the decision made by the body controller.
A camera body used in a camera system along with an interchangeable lens unit having an imaging optical system configured to form an optical image of the subject, a focus adjuster configured to optically adjust the focus state of the optical image, and a lens controller configured to control the operation of the focus adjuster, the camera body comprising:
- an imaging unit configured to convert an optical image of the subject into an image signal and configured to acquire an image of the subject;
- a focus detector configured to detect the focus state of the optical image by contrast detection method on the basis of the image signal;
- and
- a body controller configured to control the operation of the imaging unit and with which information can be exchanged with the lens controller,
- wherein the lens controller has lens information related to the interchangeable lens unit,
- the lens information includes information related to whether or not a method for driving the focus adjustment of the interchangeable lens unit is compatible with wobbling,
- the body controller is configured to decide whether or not a method for driving the focus adjustment of the interchangeable lens unit is compatible with wobbling based on the lens information, so that a focusing performance can be set based on the decision made by the body controller.
