Claim 16:
17. A camera system comprising:
an image pickup apparatus communicably mountable with a lens apparatus; and
a lens apparatus that includes a driver configured to drive a driven member, a transmitter configured to transmit information on the lens apparatus to the image pickup apparatus, and a controller configured to control driving of the driver using an instruction from the image pickup apparatus on a control over the driver based on information on a magnetic noise source,
wherein the image pickup apparatus includes an acquirer configured to acquire the information on the magnetic noise source, and a determiner configured to determine the control over the driver using the information on the magnetic noise source,
wherein when distance information from an image sensor to the magnetic noise source changes from first distance information to second distance information in a case where the driven member moves from a first position, corresponding to the first distance information, to a second position, corresponding to the second distance information, in an optical axis direction, the acquirer acquires from the lens apparatus the distance information that has been changed.
