Abstract
An optical apparatus attachable to and detachable from an image pickup apparatus includes an aperture stop configured to change an aperture value, a first optical member configured to change an aberration by being inserted into and removed from an optical path, one or more memories storing instructions, and one or more processors that, upon execution of the instructions, operate to perform processing regarding the aperture stop in accordance with a first aperture value that limits a variable range of the aperture value, and a second aperture value transmitted from the image pickup apparatus. The first aperture value is determined based on an optical characteristic of the first optical member.
Claims16
An optical apparatus attachable to and detachable from an image pickup apparatus, the optical apparatus comprising:
- an aperture stop configured to change an aperture value;
- a first optical member configured to change an aberration by being inserted into and removed from an optical path;
- one or more memories storing instructions;
- and
- one or more processors that, upon execution of the instructions, operate to perform processing regarding the aperture stop in accordance with a first aperture value that limits a variable range of the aperture value, and a second aperture value transmitted from the image pickup apparatus,
- wherein the first aperture value is determined based on an optical characteristic of the first optical member.
An image pickup apparatus attachable to and detachable from an optical apparatus that includes an aperture stop and a first optical member configured to change an aberration, the image pickup apparatus comprising:
- an image sensor;
- one or more memories storing instructions;
- and
- one or more processors that, upon execution of the instructions, operate to:
- acquire a first aperture value that defines a movable range of the aperture stop, which is determined based on an optical characteristic of the first optical member, and
- adjust an exposure amount to the image sensor,
- wherein in a case where the first aperture value is acquired, the one or more processors operate to set an aperture value for the aperture stop to the first aperture value, and switch an exposure adjustment method from a first method to a second method.
