ABSTRACT:
A clamping device for a camera accessory such as a hood includes a generally tubular attachment portion forming a part of the accessory for attachment to a camera lens mount or a pre-assembled, telescoping hood arranged on a lens mount. A number of projecting members extend radially inwardly from the inner circumference of the attachment portion to contact the outer periphery of the lens mount or pre-assembled hood. An engagement member extends through the attachment portion and is urged by a spring to contact the outer periphery of the lens mount or pre-assembled hood so that the engagement member, together with the projecting members, operate to fix the accessory on the lens mount or pre-assembled hood.
