Abstract
A camera accessory is equipped with an accessory mount assuming a bayonet structure with first through third tabs set over intervals along a circumference and projecting from inside of the accessory toward the outside. The mount is structured so that insertion of the mount is allowed when the mount is inserted at a correct interlock phase without any of the first through third tabs contacting any of three camera body-side tabs, and that insertion of the mount is disallowed if the accessory mount is positioned at an incorrect interlock phase with at least two tabs contacting at least two of the camera body-side tabs. The first through the third tabs extend along varying lengths along the circumference. When the first tab and either other tab contacts two of the camera body-side tabs at a total of two contact locations, the first tab contacts near the second side end.
