An image capturing apparatus capable of obtaining an effect that good focus is maintained during zooming even if thermal expansion of a lens barrel occurs due to a temperature rise. The image capturing apparatus includes an imaging optical system that includes a first lens movable in an optical axis direction, a first motor that moves the first lens, a position sensor that detects a position of the first lens, a memory device that stores instructions, and a processor that executes the instructions to control movement of the first lens by outputting a control signal to the first motor to move the first lens from a reference position to a target position, calculate a difference between the position of the first lens detected by the position sensor and the target position, and allow to change the reference position based on a shift amount of an image plane obtained from the difference.
An image capturing apparatus comprising:
A control method for an image capturing apparatus providing an imaging optical system that includes a first lens movable in an optical axis direction, the control method comprising:
A non-transitory computer-readable storage medium storing a control program causing a computer to execute a control method for an image capturing apparatus providing an imaging optical system that includes a first lens movable in an optical axis direction, the control method comprising:
