Claim 15:
16. A lens apparatus communicably mountable on an image pickup apparatus, the lens apparatus comprising:
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 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 transmitter transmits the distance information that has been changed to the image pickup apparatus.
