  • Patent number: 11451702
    Abstract: The present technique relates to a lens apparatus, a driving method, an image capturing apparatus, and an image capturing system that allow reduction of possible noise in a captured image caused by a magnetic field generated when an actuator of the lens apparatus is driven, without any change in image capturing processing of the image capturing apparatus. A lens apparatus is enabled to be mounted on an image capturing apparatus and includes an actuator, a communication section configured to receive, from the image capturing apparatus, drive frequency information used to set a drive frequency for the actuator, a control section configured to set the drive frequency for the actuator on the basis of the drive frequency information, and a driving section configured to drive the actuator at the drive frequency set. The present technique can be applied to, for example, a lens apparatus mounted on a single-lens reflex camera.
