Optical image stabilization apparatus, lens apparatus, and image capturing apparatus

A lens apparatus comprising:

• an optical image stabilization apparatus and
• a lens barrel configured to accommodate the optical image stabilization apparatus and to hold a lens,
• wherein the optical image stabilization apparatus comprising:
• a movable member configured to hold an optical element;
• a base member configured to hold the movable member to be movable in a direction including a component orthogonal to an optical axis of the optical element;
• a first position detection unit configured to detect a position of the movable member with respect to the base member in a direction of a first detection axis parallel to a plane orthogonal to the optical axis;
• a first driving unit configured to drive the movable member with respect to the base member in a direction of a first drive axis parallel to the plane orthogonal to the optical axis,
• a second position detection unit configured to detect a position of the movable member with respect to the base member in a direction of a second detection axis parallel to a plane orthogonal to the optical axis;
• and
• a second driving unit configured to drive the movable member with respect to the base member in a direction of a second drive axis parallel to the plane orthogonal to the optical axis,
• wherein the first driving unit includes a coil and a magnet that is arranged at a position facing a direction along the optical axis with respect to the coil,
• wherein the first position detection unit is arranged at a position facing the direction along the optical axis with respect to the magnet and detects a position of the movable member in a direction of the first detection axis by detecting a change in a position of the magnet,
• wherein, as viewed along the optical axis, the first detection axis is inclined with respect to the first drive axis, and
• wherein the first detection axis and the second detection axis are not orthogonal to each other.
