This is a very basic twin lens reflex camera. The top lens is for viewing and the lower lens is for taking the picture. You open a lid on the top, and look down into the camera to compose the picture. There is no way to adjust the focus, aperture or exposure. The only control is to select time exposure mode (aka bulb), where the shutter stays open as long as you hold the release. Overall condition is excellent with only light wear, although we have not tested it with film. It takes 620 roll film. Kodak no longer makes this film, but there are some alternative suppliers online.
