Novoflex EOS/NIK-NT Lens Adapter for Nikon G Type Lenses to Canon EOS DSLR Cameras 
The Novoflex EOS/NIK-NT Lens Adapter allows a Nikon G type (no manual aperture ring) lens to be mounted onto Canon EOS Digital SLR cameras. The adapter is equipped with an integrated aperture control ring for manual exposure control.
Although the lens will fit physically, automatic diaphragm (AE metering), or any other functions, are not retained using this adapter. The adapter does not transfer any function from the camera body to the lens.
