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 -NT version differs from the existing EOS/NIK adapter through the addition of a mechanical lever that lets users control the aperture on Nikkor G-series lenses. The adapter provides a mechanical connection between the lens and the body which allows focusing to infinity but retains automatic metering for aperture priority mode.
You will need to meter in “stop-down mode” since the lens does not have the ability to have its aperture controlled by the camera body.
This adapter provides no electronic communication between the camera and lens. All aperture and focus adjustments must be made manually on the lens itself. The aperture selected will not be displayed on the camera, and it will not show up in the EXIF data.
