This hard wearing bronze mount adapter ring allows you to use the majority of Nikon F and AI lenses [auto or manual focus] on your Canon EOS camera, saving you the expense of a costly and irreversible conversion. To use, simply attach the ring to your lens and then the lens to the camera. When you have finished remove both together. It's as easy as that! On compliant models this enables you to get stop down manual exposure and aperture priority exposure.

The adapter ring is compatible with the Canon 10D, 20D, 1D, 1Ds and 350D models, however, please be aware that it does not work with the digital Nikon DX lenses which do not cover the full 35mm film format.

Adapter ring is brand new, has never been used and comes in its original box.V1.0
