K&F Concept NIK F(G)-M4/3 Pro – Nikon F (G) Lens to Micro 4/3 Mount Adapter

The K&F Concept NIK F(G)-M4/3 Pro adapter mounts lenses with the Nikon F mount on cameras with the Micro 4/3 mount. It is purely mechanical, with no electronic contacts: focusing is done by hand on the lens and the aperture of Nikon G lenses is set with the ring on the adapter, while infinity focus is retained. The all-metal adapter is precisely machined and coated inside with matte anti-reflection paint.

Nikon F (G) lenses on Micro 4/3 bodies

With the NIK F(G)-M4/3 Pro adapter, Nikon F (G) lenses can be used on a modern Micro 4/3 body with everything it offers – a viewfinder with magnification for precise manual focusing, sensor stabilisation if the body has it, and current recording formats. The length of the adapter matches the difference in flange distance between the two systems, so the lens focuses across its whole range, all the way to infinity.

Solid metal construction

The adapter is all-metal, made of hardened anodised aluminium. Precise machining ensures a firm connection without play. The interior is coated with matte paint that absorbs stray light and reduces reflections and flare.

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. Nikon G lenses have no aperture ring, so their aperture is set with the ring on the adapter. Lenses with their own aperture ring (Nikon AI, AI-S) are stopped down on the lens.

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

Olympus PEN, OM-D, Panasonic Lumix G, GH, GX, GF, Blackmagic Pocket Cinema Camera and other bodies with the Micro 4/3 mount.
