Abstract
Abstract A tubular structure having at one end a bayonet or screw mounting device is proportioned to interfit with a complementary lens mounting device on a single lens reflex camera, so that by removal of the camera lens from the camera the device may be connected with the camera. The camera lens may be mounted within the device and thereby utilized as the optical system of the conversion device. The tubular structure further has a light inlet or light source associated with its end remote from the camera end, and the tubular structure is slotted intermediate the light source end and the position of the lens when mounted in the device so that a slide or transparent element having a photographic image thereon may be inserted in the slot and may be directly converted by operation of the camera. Provision is also made for insertion of a correction filter.
