• Front side - accepts lenses with Nikon F mount
• Rear side - fits cameras with Canon EF mount

This is a Chinese adapter. I guess it is made from brass, and nickel-plated.

The adapter has a lens lock/release mechanism, and overall quality is high. The fit is reasonably tight and reliable.

Due to the adapter is very thin, it has the lens release button on the inside. This means that you cannot remove the lens from the adapter when it is installed on the camera. It is necessary to remove the lens with the adapter from the camera first, and then you can remove the adapter from the lens. You can consider such an adapter as the add-on lens mount therefore.

This adapter has the AF confirmation chip.
