Communication apparatus that sends signal for instructing image pickup apparatus to execute shooting operation and communication control method therefor

A communication apparatus configured to be removably mounted on an image pickup apparatus, comprising:

• a memory device;
• and
• a processor configured to execute computer executable instructions recorded on the memory device, the computer executable instructions including instructions, that when executed by the processor, cause the communication apparatus to:
• send a first signal for instructing execution of a shooting operation to the image pickup apparatus via a cable connected to the image pickup apparatus;
• send a second signal for instructing execution of the shooting operation to the image pickup apparatus via a signal terminal that is electrically connected to a terminal provided in an accessory shoe of the image pickup apparatus;
• and
• control, according to a state of the image pickup apparatus, the communication apparatus to send either the first signal or the second signal to the image pickup apparatus to instruct execution of the shooting operation,
• wherein in a case where the image pickup apparatus is connected to the cable, able to communicate with the communication apparatus via the terminal provided in the accessory shoe, and in a manual focus mode, the communication apparatus is caused to send the first signal to the image pickup apparatus.

• and
• a processor configured to execute computer executable instructions recorded on the memory device, the computer executable instructions including instructions, that when executed by the processor, cause the communication apparatus to:
• send a first signal for instructing execution of a shooting operation to the image pickup apparatus without involving a signal terminal that is electrically connected to a terminal provided in an accessory shoe of the image pickup apparatus;
• send a second signal for instructing execution of the shooting operation to the image pickup apparatus via the signal terminal;
• and
• control, according to a state of the image pickup apparatus, the communication apparatus to send either the first signal or the second signal to the image pickup apparatus to instruct execution of the shooting operation,
• wherein information as to whether the image pickup apparatus can execute the shooting operation in response to the second signal is obtained via the signal terminal, and
• wherein in a case where the image pickup apparatus is able to receive the first signal and communicate with the communication apparatus via the terminal provided in the accessory shoe, a signal to be sent to the image pickup apparatus when execution of the shooting operation is instructed is switched between the first signal and the second signal based on the obtained information.

A method for a communication apparatus configured to be removably mounted on an image pickup apparatus and to send a signal for instructing execution of a shooting operation to the image pickup apparatus, comprising:
