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 tab, the second tab and the third tab extend over varying lengths along the circumferential direction. The first tab extends over a greatest length along the circumferential direction among the first through third tabs. The third tab extends over a smallest length along the circumferential direction among the first through third tabs. The accessory mount includes a restricting member disposed near the third tab, a fitting portion used to align an optical axis of the accessory mount with an optical axis of the camera body, and a lock pin hole through which a lock pin, retractably disposed at the camera body, is inserted so as to lock the camera accessory in a fully mounted state. The restricting member is disposed at a position assumed on a side substantially opposite from the lock pin hole across the fitting portion.
