Photographing apparatus and control method for photographing apparatus

A control method for a photographing apparatus that comprises

• a lens barrel including a photographing optical system for guiding shooting light flux,
• a camera body to which the lens barrel can be removably attached,
• an image sensor having pairs of focus detection pixels,
• a first memory, provided in the lens barrel, for storing information relating to incident angle range of imaging light flux on the image sensor, and
• a second memory, arranged in the camera body, for storing information on light receiving sensitivity characteristic of the focus detection pixels, the control method comprising
• calculating information for focus adjustment control based on information that has been read out from the first memory and the second memory, the information relating to incident angle range including angular information of upper and lower ends of imaging light flux corresponding to image height, and
• calculating incident angle range for light flux incident on the focus detection pixels based on the information relating to incident angle range.

A non-transitory computer-readable medium storing a computer program for controlling a photographing apparatus wherein the photographing apparatus comprises:

• a lens section including a photographing optical system for guiding shooting light flux,
• a camera body to which the lens barrel can be removably attached,
• an image sensor having pairs of focus detection pixels,
• a first memory, provided in the lens barrel, for storing information relating to incident angle range of imaging light flux on the image sensor, and
• a second memory, arranged in the body section, for storing information on light receiving sensitivity characteristic of the focus detection pixels, the computer program comprising
• calculating information for focus adjustment control based on information that has been read out from the first memory and the second memory,
• wherein
• the information relating to incident angle range includes angular information of upper and lower ends of imaging light flux corresponding to image height, and
• incident angle range for light flux incident on the focus detection pixels is calculated based on the information relating to incident angle range.
