Abstract
Abstract An accessory attachment for use with a camera of the type having a frontal generally parallelepiped housing for an objective lens, a shutter mechanism, and camera function-controlling devices such as photocells and shutter or control knobs or buttons. The attachment serves to mount accessories such as auxiliary portrait, wide-angle, or telephoto lenses, filter lenses for the camera's objective lens and photocell, auxiliary shutter or control knobs, and flash equipment, in aligned operative relation to the corresponding elements of the camera. The attachment comprises a housing mounting the accessories in a front portion, and a pair of wing portions extending rearwardly to embrace the side walls of the lens-shutter housing, and bearing a pair of opposed latch portions which releasably engage rear corner portions of the side walls. Locating flanges in the side walls of the lens-shutter housing align the attachment correctly with the camera. A pair of actuating levers may be connected with the latch portions and extended forwardly of the housing into opposed grip portions for manual deflection of the latch portions to disengage the attachment from the camera.
