Abstract
The interchangeable lens includes a lens holding member holding a lens, a first supporting bar engaging with the lens holding member to guide movement of the lens holding member in an optical axis direction, a second supporting bar engaging with the lens holding member to prevent rotation of the lens holding member, the second supporting bar having a shorter length than that of the first supporting bar. The interchangeable lens further includes a mount contact provided as an electric contact in a mount portion detachably attachable to a camera body. When viewed from the optical axis direction, the first supporting bar is disposed in an area not overlapping the mount contact, and the second supporting bar is disposed in an area overlapping the mount contact, and when viewed from a direction orthogonal to the optical axis direction, part of the first supporting bar overlaps the mount contact.
