Image capturing apparatus, lens apparatus, and data communication process program

A lens apparatus detachably attached to the image capturing apparatus and communicate with the image capturing apparatus, the lens apparatus comprising:

• a registration unit configured to register command registration information indicative of a combination and a transmittance order of a plurality of lens data to be transmitted to the image capturing apparatus in response to the command registration information received from the image capturing apparatus;
• and
• a data transmitter configured to transmit the plurality of lens data to the image capturing apparatus in the transmission order based on the command registration information in response to a transmission request command corresponding to the command registration information received from the image capturing apparatus.

An image capturing system that includes an image capturing apparatus, and a lens apparatus detachably attachable to the image capturing apparatus,

• wherein the image capturing apparatus includes a command registration requester configured to send to the lens apparatus command registration information indicative of a combination and a transmission order of a plurality of lens data to be transmitted from the lens apparatus to the image capturing apparatus, and a transmission requester configured to request the lens apparatus to transmit the plurality of lens data in the transmission order based on the command registration information, and
• wherein the lens apparatus includes a registration unit configured to register the command registration information in response to the command registration information received from the image capturing apparatus, and a data transmitter configured to transmit the plurality of lens data to the image capturing apparatus in the transmission order based on the command registration information in response to a transmission request command corresponding to the command registration information received from the image capturing apparatus.

A non-transitory recording medium which stores a data communication process program as a computer program that enables a computer in an image capturing apparatus to which a lens apparatus is detachably attached, to implement a data communication process, wherein the data communication process includes:

• sending command registration information indicative of a combination and a transmission order of a plurality of lens data to be transmitted from the lens apparatus to the image capturing apparatus;
• and
• receiving the plurality of lens data sent from the lens apparatus in the transmission order based on the command registration information.
