Problems solved by technology

[0009] However, in the above technology, only the control signal sent from the camera body is converted into a control signal in a mode that enables interchangeable lenses, and the AF operation and the like are restricted due to the difference in the control mode.
Therefore, when an interchangeable lens of a different camera system is attached to the camera body, the operation instructed by the camera body cannot be performed properly due to the difference in the lens control method.

Abstract

The invention provides a changeable joint which can make a changeable lens correctly execute indicated actions under the condition that an assembly control mode of a main body of a lens-changeable camera system is different from the changeable lens. The changeable joint which is taken as a solving method includes a shaking lens (401b) which can adjust the focus state of a shooting element (203) on a shooting face and a joint control part (408) can divide an action order transmitted from the main part (3) and indicating the action of a lens part (3) and the shaking lens (401b) into a lens order executed by the lens part (3) and an optical system order executed by the shaking lens (401b). The lens order is converted into a control mode of the lens part (3) and is transmitted to the lens part (3), so the shaking lens (401b) executes an action which is corresponding to the optical system order.

Description

technical field [0001] The present invention relates to an interchangeable lens camera system, and relates to an interchangeable joint for attaching an interchangeable lens unit of another interchangeable lens camera system to a camera main body. Background technique [0002] In recent years, video equipment has made remarkable progress, especially in the field of imaging devices. The silver halide film that captures images has been replaced by an imaging element to achieve digitization, and interchangeable lens camera systems with new mounting specifications have been proposed and commercialized. [0003] However, when using an interchangeable-lens camera system with a new mount specification, a new mount-use interchangeable lens must be purchased, and an existing mount-size interchangeable lens cannot be used, which may cause dissatisfaction among users. [0004] Accordingly, there has been proposed an interchangeable joint for attaching an interchangeable lens of an exist...
