Lens apparatus, image pickup apparatus, and imaging system

An image pickup apparatus comprising:

• a lens apparatus;
• an imaging element;
• wherein the lens apparatus includes:
• an optical member movable according to control by each of a plurality of operation units;
• one or more memories storing commands;
• and
• one or more processors that, upon execution of the commands, operate to:
• determine a first operation unit for moving the optical member from the plurality of operation units, and
• move the optical member according to information on at least one of a target position and a speed of the optical member set by the first operation unit,
• wherein the lens apparatus includes a predetermined function, and
• wherein the one or more processors operate to determine an operation unit which transmits a signal regarding activation and deactivation of the predetermined function at an earliest timing among the plurality of operation units, as the first operation unit,
• wherein each of the plurality of operation units includes:
• a first operation member configured to switch the activation and the deactivation of the predetermined function,
• a second operation member configured to change the target position, and
• a third operation member configured to change the speed.

An imaging system comprising:

• a lens apparatus,
• an image pickup apparatus including an image sensor, and
• an external apparatus that is at least one of a plurality of operation units,
• wherein the lens apparatus includes:
• an optical member movable according to control by each of a plurality of operation units;
• one or more memories storing commands;
• and
