An exchangeable lens includes: a camera lens mount unit having a mount center point, to which a camera body, with twelve body connector terminals disposed near a camera body mount unit at the camera body, is attached; a holding portion where twelve lens connector terminals, each connected to one of the twelve body connector terminals and each including a contact area to come into contact with one of the body connector terminals, are disposed; an optical system that includes a drive target member which can be driven; and a drive unit that drives the drive target member. A distance setting apart a center of at least one lens connector terminal among the twelve lens connector terminals from the mount center point is different from a distance setting apart a center of at least one other lens connector terminal from the mount center point.
