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.

Abstract: A camera accessory can be detachably engaged with a camera body that includes a camera body mount, and is equipped with an accessory mount assuming a bayonet structure with a first tab, a second tab and a third tab set over intervals in a circumferential direction running along a circumference of a circle and projecting from the circumference along a radial direction. The 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 accessory mount includes a restricting member disposed near the third tab.
