ABSTRACT:
A lens barrel bayonet device is formed from two rings having corresponding claw portions arranged to engage mating claw portions on a camera body. In a preferred embodiment, the rings are joined together so that the claw portions of one of them also serve to seat spring members which engage the camera body when the lens barrel is mounted thereon. The spring members act to maintain the lens barrel steadily at a position where the optical axes of the lens and camera coincide with each other.
