Lens apparatus, imaging apparatus and camera system

A camera system comprising:

• a lens apparatus;
• and
• a camera body comprising an imaging element and being capable of holding the lens apparatus,
• the lens apparatus comprising:
• an imaging optical system including a plurality of lenses;
• a focus position change unit configured to change a position of a focal plane by changing a focus position based on driving of at least one of the plurality of lenses;
• an operation unit configured to operate the driving of the at least one of the lenses by the focus position change unit;
• an operation amount detection unit configured to detect an operation amount of the operation unit;
• a tilt driving unit configured to change a tilt of the focal plane by driving the imaging optical system so that the imaging optical system is inclined;
• a tilt amount detection unit configured to detect a tilt amount that is a drive direction and a drive amount of the imaging optical system by the tilt driving unit;
• and
• a control unit configured to change a unit drive amount with respect to the operation amount in the focus position change unit by using the tilt amount.
