Abstract
Abstract An accessory foot fixed to an accessory such as a strobo flash light unit has a demountable foot member in addition to a standardized foot part. The demountable foot member is removably mounted to the foot to elongate the length of the standardized foot part to be inserted into a shoe fixed to a camera body. The elongated foot is engaged with a specially designed long accessory shoe to firmly hold the accessory on the camera body. When the accessory is mounted to a camera body with an ordinary standard accessory shoe, the demountable accessory foot member is removed from the accessory so that the standardized foot part of the foot may be accommodated with the standard accessory shoe.
