This is a review of the Novoflex Nikon to Canon Lens Adapter, also known as “Novoflex EOS/NIK-NT Lens Adapter”. This lens adapter is designed to be used specifically with Nikon G lenses that have no aperture rings. While most generic lens adapters can be easily used with older non-G Nikon lenses and you can easily control aperture by just rotating the aperture ring on the lens, there is no way to control aperture on all modern “G” type lenses with such an adapter. So if you used a generic lens adapter, you would be limited to shooting at minimum aperture of the lens (default) and there would be no physical way to adjust it while the lens is attached to the camera. To allow manual change of aperture on these types of lenses, Novoflex specifically designed an adapter with an aperture lever. In this review, I will talk about the pros and cons of using the Novoflex adapter and my overall experience with it when mounting Nikon lenses on Canon DSLRs.
