Abstract:
An accessory mount can be inserted through the camera body mount without any of the first through third tabs being hindered by any of three camera body-side tabs at the camera body mount, as long as the accessory mount is inserted into the camera body mount at a correct interlock phase. The first, second, and third tabs extend over varying lengths along the circumferential direction. The first tab extends over a greatest length and the third tab extends over a smallest length, along the circumferential direction. The accessory mount includes a restricting member, a fitting portion, and a lock pin hole. The restricting member is disposed at a position assumed on a side substantially opposite from the lock pin hole across the fitting portion.

Claim (Index 1):
A camera accessory that can be detachably mounted to a camera body that includes a camera body mount, the camera accessory including an opening forming member having an optical path at its inner circumferential side and being equipped with an accessory mount having a bayonet structure with a plurality of tabs (i) disposed at a circumferential surface of the opening forming member over intervals in a circumferential direction running along the circumferential surface and (ii) projecting outward from the circumferential surface, wherein:\n the plurality of tabs are disposed at the accessory mount so that the plurality of tabs can be inserted through the camera body mount without any of the plurality of tabs being hindered by any of a plurality of camera body-side tabs at the camera body mount when the accessory mount is inserted into the camera body mount at a predefined positional relationship; the plurality of tabs extend over varying lengths along the circumferential direction; and the plurality of tabs at the accessory mount are arranged to become engaged with the plurality of camera body-side tabs, respectively, when the accessory mount is rotated along a counterclockwise direction by approximately 40.5\u00b0 from the predefined positional relationship with respect to the camera body mount.
