Novoflex Adapter Allows the Mounting of Nikon Lenses (including G Series) on an EOS Camera Body.
All Novotron Lens adaptor rings retain the lens ability to focus on infinity. They do not transmit any functions between the body and the lens.
Most cameras provide the ability to do "stopped down metering" with the diaphragm stopped down or allow an aperture priority automatic exposure, so the Lens adaptor ring will allow you to end up with a correctly exposed shot with the use of lenses from other manufacturers on various cameras.
This adapter allows the use of Nikon lenses that do not come with a manual aperture control ring (Nikkor G series) due to an integrated aperture control ring.
