Made of black anodized aluminum the KIWIFOTOS LMA-M39_N1 mount adapter will allow you to use Leica Thread Mount M39 (LTM) lenses on any Nikon 1 mount camera body (Nikon 1 J1, Nikon 1 V1 etc.).
The lens will fit physically, auto-focusing control and camera modes which control exposure by automatically adjusting aperture are not retained, however. Preserve all focusing range up to the infinity point.
