A precision-made body adapter to fit Nikon-G lenses on a Canon EOS camera body, retaining infinity focus, but losing all other connections. The adapter includes a ring to stop down the aperture on Nikon-G lenses, and can be used with other Nikon lenses as well. Made in Germany to tight tolerances, this results in negligible play between the adapted lens and body. Can be used on any Nikon lens except tilt and shift types.
