This adapter tube consists of three individual Tubussen, which are screwed to each other to vary the length of the entire tube. The shortest adapter tube is used for wide-angle lenses, the longest for telephoto lenses, in which the camera lens itself can extend maximum.
The Adaptertubusse act on the material and its varnish pleasant quality and a perfect fit on the lens mount with the fluted bezel of the Nikon Coolpix P7700 (see my clients pictures).
