The startup state providing terminal is disposed adjacent to the data signal terminal, and the first reference potential terminal is adjacent to the data signal terminal, and is disposed with the data signal terminal interposed between the startup state providing terminal and the first reference potential terminal.

Accessory, camera, accessory shoe, and connector

An accessory which is controlled by a control signal supplied from a camera, includes: a terminal section having a plurality of terminals located adjacent to each other in an array that extends in an array direction, the plurality of terminals including at least a power terminal to which power is supplied from the camera and a signal input terminal to which the control signal is input from the camera; and a ground portion corresponding to the power terminal. The power terminal is disposed at a first end of the array the signal input terminal is disposed near a second end of the array opposite the first end, and the ground portion is disposed in a position further away from the power terminal than is the signal input terminal.

Electronic flash device

A lighting system of the present invention includes a master flash device, a remote flash device, a support part, and a light guiding member. The master flash device emits light in accordance with a light emission control of a camera. The remote flash device has a light-receiving part that receives the light of the master flash device and emits light in accordance with the light-receiving result of the light-receiving part. The support part has the remote flash device mounted at a place where the light of the master flash device is shielded by a shooting lens or a camera. The light guiding member optically forms a detour optical path that guides the light of the master flash device to the light-receiving part.
