Abstract
A clamping device for camera accessories includes a cylindrical adaptor member defining a lens hood. The inner periphery of the adaptor member is formed with an annular collar member which has an internal diameter smaller than the external diameter of a collar formed on the outer sleeve of a lens barrel along a V-shaped groove which is formed on the outer periphery of the outer sleeve. The collar member serves to prevent the hood from connecting with the lens barrel at an undesirable position.
