What is Nikon Lens Scope Converter (LSC)?
In short - it is the thing that you attach to your lens like teleconverter and which includes an erecting eyepiece with 10mm focal lenght. With this thing, your Nikon mount lens turns into the spotting scope!

Scope technics!
Little more information about the LSC and the scope technics! The magnigication of the scopes is determined by the focal lenght of the lens and the focal lenght of the eyepiece... and it works same with the camera lenses with LSC. Focal lenght of the lens divided by focal lenght of the eyepiece is the magnification. So with 300mm lens and LSC attached you get 300mm / 10mm = 30... So when using 300mm lens and Nikon lens scope converter, you get the scope with magnification of 30x. Similarly when using an 70-200 lens, you get an 7-20x scope.
