A few important accessories are needed to hang your night vision in front of a camera. These accessories almost always are not standard accessories, so confirm this before you place an order. Let's start with the 35mm film camera situation. You need a relay lens and a T ring. A relay lens threads in where the eyepiece normally lives. Its job is to focus the image from the intensifier onto the appropriate place (optics or film) in the camera. And, actually, the image produced by the intensifier is upside down and backwards. You can see this if you look through the thing without the eyepiece attached. Another function of the relay lens is to turn the image right side up and forward again so everything comes out properly in the end.
