Lens driving adapter, lens apparatus and image capturing apparatus

A lens apparatus comprising:

• a lens barrel to which a lens driving adapter is detachably attachable;
• and
• an operation member provided on the lens barrel,
• wherein the lens driving adapter comprises:
• a driver configured to drive the operation member of the lens barrel to which the lens driving adapter is attached;
• and
• an adapter body holding the driver,
• wherein:
• the adapter body includes a first contact portion and a second contact portion that are protrusions contactable with two circumferential portions in an outer circumferential surface of the lens barrel, the two circumferential portions being disposed at different positions away from the operation member;
• the first and the second contact portions each have a shape that convexes toward the outer circumferential surfaces of the lens barrel;
• and
• the adapter body includes a fixing member configured to fix the adapter body to the lens barrel.

An image capturing apparatus comprising:

• a lens barrel to which a lens driving adapter is detachably attachable and on which an operation member is provided,
• an image sensor configured to capture an object image formed by an image capturing optical system housed in the lens barrel,
• wherein the lens driving adapter comprises:
• a driver configured to drive the operation member of the lens barrel to which the lens driving adapter is attached;
• and
• an adapter body holding the driver,
• wherein:
• the adapter body includes a first contact portion and a second contact portion that are protrusions contactable with two circumferential portions in an outer circumferential surface of the lens barrel, the two circumferential portions being disposed at different positions away from the operation member;
• the first and the second contact portions each have a shape that convexes toward the outer circumferential surfaces of the lens barrel;
