5 . The image pickup apparatus according to claim 1 , further comprising a display unit configured to display a first captured image obtained by imaging through the first optical system and a second captured image obtained by imaging through the second optical system,

wherein the processor is configured to:

perform the focus control of the first optical system by displaying the first target position on the first captured image, and

perform the focus control of the second optical system by displaying the second target position on the second captured image after the focus control of the first optical system is completed.

6 . The image pickup apparatus according to claim 5 , wherein the processor is configured to:

cause the display unit to display an enlarged image of a portion of the first captured image that includes the first target position, and

cause the display unit to display an enlarged image of a portion of the second captured image that includes the second target position.

7 . The image pickup apparatus according to claim 4 , further comprising a display unit configured to display a first captured image obtained by imaging through the first optical system and a second captured image obtained by imaging through the second optical system,

wherein the processor is configured to perform the focus control of the first optical system by displaying the first target position on the first captured image and the focus control of the second optical system by displaying the second target position on the second captured image.

8 . The image pickup apparatus according to claim 4 , wherein the processor is configured to control a first drive unit configured to drive the first optical system in the focus control of the first optical system and a second drive unit configured to drive the second optical system in the focus control of the second optical system.
