Interchangeable lens

An interchangeable lens removably attachable to a camera body that includes:

• an image sensor onto which a subject light is incident;
• a body-side terminal group disposed in an arc shape outside the image sensor;
• a body-side mount having a ring shape disposed outside the body-side terminal group;
• a plurality of body-side projecting portions each projecting inwardly from the body-side mount;
• and
• a plurality of elastic members respectively disposed at an image side of the plurality of body-side projecting portions, the interchangeable lens comprising:
• a lens-side mount that is configured to contact with the body-side mount with the interchangeable lens being attached to the camera body;
• a cylindrical portion extending from an inner peripheral edge of the lens-side mount in an optical axis direction of the subject light;
• and
• a plurality of lens-side projecting portions (i) projecting outwardly from the cylindrical portion, (ii) extending in the circumferential direction of the cylindrical portion, and (iii) comprising first, second, third, fourth, and fifth lens-side projecting portions, wherein:
• of the plurality of lens-side projecting portions:
• the fifth lens-side projecting portion has a fifth longest length in the circumferential direction;
• and
• the fourth lens-side projecting portion has a fourth longest length in the circumferential direction;
• and
• the first lens-side projecting portion is disposed at a position facing at least a part of the fifth lens-side projecting portion and at least a part of the fourth lens-side projecting portion across the optical axis.
