Abstract
An interchangeable lens apparatus attachable to an imaging apparatus configured to move an image sensor in an image stabilization includes an imaging optical system, a storage unit configured to store image circle information including a relationship between an imaging condition and position information of an image circle of the imaging optical system, and a transmission unit configured to transmit at least part of the image circle information to the imaging apparatus.
Claims16
An interchangeable lens apparatus attachable to an imaging apparatus, the interchangeable lens comprising:
- an imaging optical system;
- a storage unit configured to store first information (i) on a relationship between each of a plurality of types of parameters of an imaging condition and position information of an image circle of the imaging optical system and (ii) including image circle center information of the imaging optical system, the stored first information being utilized by the imaging apparatus to increase a shiftable range of an image sensor in the imaging apparatus during image stabilization;
- and
- a transmission unit configured to transmit at least part of the first information to the imaging apparatus.
A control method for an interchangeable lens apparatus including an imaging optical system and attachable to an imaging apparatus, the control method comprising:
- storing first information (i) on a relationship between each of a plurality of types of parameters of an imaging condition and position information of an image circle of the imaging optical system and (ii) including image circle center information of the imaging optical system, the stored first information being utilized by the imaging apparatus to increase a shiftable range of an image sensor in the imaging apparatus during image stabilization;
- and
- transmitting at least part of the first information to the imaging apparatus.
