The Newcon Optik Camera and Video Adapter Assembly allows night-time photography and recording through night vision monoculars or binoculars NVS-7 and NVS-14. To install this assembly on your NVD, you remove the eyepiece and replace it with the adapter.
The adapter threads fit camcorder lenses with 37mm filter thread and camera lenses with a 52mm filter thread. If your lens in use has a 52 or 37mm filter thread, you will not need any additional accessories. If your lens has a filter thread larger than 37 or 52mm, you will need a stepdown ring which begins with your lens' filter size and ends with 52 or 38mm. If your lens has a filter size which is smaller than 52 or 37mm, you will need a stepup ring which begins as your filter size and ends as 52 or 37mm.
