ABSTRACT:
An optical accessory includes a bayonet mount attachable to a camera body side mount and accessory side connection terminals which contact the camera body side connecting terminals when the accessory side bayonet mount is attached to the camera body side bayonet mount. The accessory side connecting terminals have their end portions arranged to project in the direction of the optical axis behind the accessory side bayonet mount. In one preferred embodiment, the optical accessory further includes a member having a projection projecting in the direction of the optical axis behind the accessory side connecting terminals. The projection is positioned on the inner circumference side of the accessory side connecting terminals and is arranged near to the accessory side connection terminals. In another preferred embodiment, the end portions of the connecting terminals have plural height differences, and a contact seat also is provided for holding the accessory side connecting terminals. The contact seat has its rear side surface in the direction of the optical axis located at substantially the same height as the accessory side connecting terminals. The contact seat is fixed by a fastener in a radial direction relative to an inner circumference surface of the accessory side bayonet mount.
