K&F Concept NIK(S)-EOS R – Nikon S Lens to Canon RF Mount Adapter

The K&F Concept NIK(S)-EOS R adapter mounts lenses with the Nikon S mount on cameras with the Canon RF mount. It is purely mechanical, with no electronic contacts: focusing is done by hand on the lens and the aperture is set with the lens aperture ring. An anti-reflection finish inside reduces reflections.

Nikon S lenses on Canon RF bodies

With the NIK(S)-EOS R adapter, Nikon S lenses can be used on a modern Canon RF body with everything it offers – a viewfinder with magnification for precise manual focusing, sensor stabilisation if the body has it, and current recording formats.

Precise connection

Precise machining ensures a firm connection without play. The inner walls have an anti-reflection finish that reduces reflections inside the adapter.

Manual focus and aperture

The adapter has no electronic contacts and the camera does not recognise the lens – autofocus, aperture control from the body and lens data in EXIF do not work. Focus with the ring on the lens; magnification or focus peaking in the viewfinder makes precise focusing easier. The aperture is set with the aperture ring on the lens; lenses without an aperture ring cannot be stopped down with this adapter.

First use

Before the first shot, enable shutter release without a lens in the camera menu (on Sony “Release w/o Lens”, a similar option on other brands). Otherwise the body will not treat the adapter without contacts as an attached lens and will not release the shutter.

Compatible cameras

Canon EOS R, RP, Ra, R5, R6 and other bodies with the Canon RF mount.
