Nikon F lenses on MFT
Yes, this works. Nikon F has a 46.5mm flange distance and Micro Four Thirds has 19.25mm, so a 27.25mm mechanical adapter with no glass fills the gap and infinity focus is preserved. Focus and aperture stay manual.

Setting it up
Enable Shoot w/o Lens (Panasonic) or leave Release Priority on (Olympus and OM System), then enter the focal length for in-body stabilisation. The 2x crop doubles the apparent focal length, so a 50mm frames like a 100mm.
Automatic diaphragm. Off the body the lens sits at the set aperture, so the aperture ring works directly on an adapter.
Nikon F lenses and their field of view on MFT
Effective focal length changes with sensor size. The lens itself does not change; the smaller sensor simply captures a narrower part of the image circle.
| Lens | Focal length | Aperture | Frames like (Four Thirds (2x)) | Years | Used value |
|---|---|---|---|---|---|
| Nikon Nikkor 105mm f/2.5 AI-S | 105mm | f/2.5 | 210mm | 1981-2005 | $150 to $450 |
| Nikon Nikkor 35mm f/1.4 AI-S | 35mm | f/1.4 | 70mm | 1976-2020s | $350 to $900 |
| Nikon Nikkor 50mm f/1.2 AI-S | 50mm | f/1.2 | 100mm | 1981-2020s | $400 to $950 |
| Nikon Nikkor-S Auto 50mm f/1.4 (pre-AI) | 50mm | f/1.4 | 100mm | 1962-1974 | $60 to $220 |
Frequently asked
Do Nikon F lenses work on MFT cameras?
Yes. A plain Nikon F to MFT adapter works with no optics. Nikon F has a 46.5mm register and Micro Four Thirds has a 19.25mm register, so the adapter is a 27.25mm tube that puts the lens exactly where a Nikon F body would. Plain adapter ring for every manual-aperture Nikkor. Pre-AI lenses mount freely on adapters; their only compatibility problem is with later Nikon bodies whose meter-coupling tab they can bend.
Do Nikon F lenses focus to infinity on MFT?
Yes. Because the adapter restores the native 46.5mm register, infinity focus is preserved and the full focus scale on the lens stays accurate. Adapters machined slightly short let the lens focus past infinity by a small margin, which is harmless; adapters machined long stop short of infinity, so buy from a maker with tight tolerances.
What focal length does a Nikon F lens become on MFT?
On Four Thirds (2x) MFT bodies (Lumix G, GH, GX; OM-D and PEN; OM-1 and OM-5) a 105mm lens frames like a 210mm lens on full frame; the aperture and depth of field at a given distance do not change.
