System and method for modifying an optical assembly with another image modifying device by using an adapter assembly to connect or couple three image modifying devices together. The adapter assembly includes two adapters that have collars to hold a night vision monocular between them, and to each connect with a camera and lens, respectively, modifying a camera-lens assembly for use in night time photo surveillance. One adapter's collar includes a gripping mechanism to grip one end of the night vision monocular. The other adapter's collar includes one or two channels to each receive a pin on the other end of the night vision monocular and a locking mechanism to secure one pin in its channel. Attachments members on each adapter include mechanical and electrical connectors to couple or connect the adapters to each other, and to electrically connect the camera with the lens.
