Abstract
The interchangeable lens apparatus includes a memory to store first correction information to be used to correct focus state information on a focus state of its image capturing optical system, the focus state being detected in the image capturing apparatus by using a signal from an image sensor thereof, and a lens calculator configured to produce, by performing an interpolation process on the first correction information by using image sensor information that is information on the image sensor and received from the image capturing apparatus, second correction information corresponding to the image sensor information. The lens calculator sends the second correction information to the image capturing apparatus in a case where the lens calculator performs the interpolation process and sends the first correction information to the image capturing apparatus in a case where the image capturing apparatus performs the interpolation process.
