The Pro Lens Mount Adapter for Rolleiflex SL66-Mount Lens to Nikon F-Mount Camera from FotodioX allows a Rolleiflex SL66-mount lens to be used with a Nikon F-mount camera. It is designed to support focusing to infinity, and is constructed with brass along with stainless steel mounting rings to provide a durable, yet lightweight camera-to-lens connection.

This adapter does not support electronic communication between an attached camera and lens. After being placed on the front of the adapter, aperture control on a compatible lens would continue to be used. For focus control, the Pro Lens Mount Adapter for Rolleiflex SL66-Mount Lens to Nikon F-Mount Camera features a built-in helicoid that extends and retracts a compatible lens in a manner similar to a Rolleiflex SL66 focusing rack.

Similar to a Rolleiflex SL66 camera's lens mounting ring, the Pro Lens Mount Adapter for Rolleiflex SL66-Mount Lens to Nikon F-Mount Camera offers the ability to mount a compatible lens in reverse. By utilizing this feature, the focal length of the attached lens relative to the camera being used is shortened, which can then provide a macro effect.

To help prevent stress on the camera mount if the supported camera and lens combination is to be placed on a tripod, the Pro Lens Mount Adapter for Rolleiflex SL66-Mount Lens to Nikon F-Mount Camera includes a detachable tripod foot that features 1/4"-20 threads.

Q: 2. Help! I am trying to use this adaptor with my Nikon AF-S NIKKOR 70-200mm f/2.8E FL ED VR on my new GFX 100s. everything mounts up but I have NO aperture control. it seems to default to wode open or fully stopped down. I cannot control the aperture at all. this is useless in this state. Is there any resolution? Thanks..

A: When your Nikkor lens is wide open, the aperture control on this Fotodiox NIKG-GFX-PRO would be utilized.

Q: 3. i got a leica 2.8 90mm elmarit-mand i want to put on my nikon f3 will this do the job ?

A: Yes. It does the job. I have already purchased a similar adapter (Pentax-K to Nikon) and it works fine. You may know you have to work in Manual focus.

Q: 4. will this work with a pentax ka mount?

A: Yes, it should work, but I have not personally tested it. As far as I know, the KA lenses are very similar to the K, but have autofocus features whereas the K lenses are manual only.Hope this helps!

Q: 5. Is this the correct adapter needed for a vintage Helios 44m lens, M42? (I am using a Nikon d600).

A: Yes, M42 is correct.

Q: 6. Hello, when I mount the adapter and lens to a Fuji GFX 50r the shutter will not release. The adapter seems fine and the camera is set to manual control. Camera works fine with Fuji lenses. And I missing something on this? Thank you

A: You need to assign the camera to shoot (relic the shutter ) without a lens , this adapter does not have electronic contacts

Q: 7. Hello. If the adapter has a lens 1.4x, does it mean that a Helios 58mm in a Nikon D5600 will become in a 113mm (58 X 1.4 X 1.4) (correction factor of the camera and correction factor of the adapter)?

A: If you are looking for the 35mm equivalent focal length of a full-frame lens with a native 58mm focal length used on a Nikon APS-C sensor with the FotodioX Pro Lens Mount Adapter for M42 Lens to Nikon F Mount Camera, the new equivalent 35mm focal length would be 121.8mm. Your math was close, but in your (58 x 1.4 x 1.4) equation, you mis-typed the camera's crop factor, which is 1.5x. As such, 58mm x 1.4 would be 81.2mm, which is the equivalent focal length when using the Fotodiox adapter on a camera with a full-frame sensor, and you would then multiply 81.2mm x 1.5, which equals 121.8mm, which would be the 35mm equivalent focal length when used on the 1.5x APS crop sensor found in the Nikon D5600 DLSR camera.

Q: 8. Approximately How much mm will be 58mm lens with this adapter?

A: The FotodioX Pro Lens Mount Adapter for M42 Lens to Nikon F Mount Camera has a 1.4x multi-coated focus correction lens. As such, you would have to multiply the focal length of the M42 lens you use with the above adapter by 1.4x to find your full-frame equivalent focal length. As such, a 58mm lens would have the equivalent focal length of a 81.2mm lens as 58mm x 1.4 = 81.2mm.

Q: 9. Hi, just wondering if this adaptor would work on my Nikon d5500 body? Thanks

A: Lens adapter did not work for my camera. I have Nikon D3200. although the lenses fit to the camera my camera did not recognize that there was actually a lens attached. Having the lens adapter did not work even in manual mode. So looking forward to using my Pentax lens again but I just can't make my camera recognize the lens so it can't focus.

Q: 10. Will this work on a Nikon D3300 with an Jupiter 8 lens?

A: As long as the lens is m42 mount it should be fine. Please note though that you will have to use the lens on full manual mode, including focus.
