This Pro Lens Adapter from Fotodiox enables the use of your Exakta/Auto Topcon lenses on Nikon F mount SLR and DSLR cameras. It features a durable brass construction with stainless steel finish and a leaf spring ensures a secure connection between the lens and adapter. Additionally, through the use of a 1.4x multi-coated focus correction lens, this adapter is designed to maintain infinity focus. This correction lens can also be removed to render the adapter as an extension tube for macro shooting.

This manual adapter does not maintain automatic lens control between the camera and lens; aperture priority or manual shooting modes should be used, as well as stop-down metering for exposure control.

Q: 1. Is this the correct adapter for Carl Zeiss Jena Biotar 58mm F2 to Nikon D800 ? Will it allow infinity focus?

A: Yes, the FotodioX Pro Lens Mount Adapter for M42 Lens to Nikon F Mount Camera can be used to mount the Carl zeiss Jena Biotar 58mm f2 lens to the Nikon D800 Digital SLR Camera.

Q: 2. I have a Z7 II camera. Will the flange distance work out correctly if I mount this adapter to a Canon EF-Nikon Z adapter?

A: When using this adapter on a Canon EF-mount to Nikon Z adapter, the flange distance would be the same as one gets when using this adapter directly on a Canon camera. So it will perform equally well on your Nikon Z7 II Mirrorless Camera as it would perform on a Canon EF-Mount camera. However, I would suggest using a different setup. The FotodioX uses an optical element to compensate for the flange distance difference of the Canon EF-Mount. With the Z7 II this optical element is not necessary and a direct adapter such as the KIPON Lens Mount Adapter for Exakta-Mount Lens to Nikon Z-Mount Camera would be a better option, BH #KIEXAKTANIKZ (https://bhpho.to/3uC9oiG). With the Kipon one is not adding an optical element into the mix, and so the lens can perform as it was originally designed to perform.

Q: 3. Hi, will this fit on a Steinheil Quinar 135/2.8? Thanks!

A: As long as your lens has an Exakta mount, the FotodioX Pro Slim Mount Adapter for Exakta Lens to Canon EOS Camera will fit.

Q: 4. What is the procedure for the removal of the adapter's internal correction lens?

A: A hammer and chisel. You probably know you will lose infinity focus. My guess you will be OK focusing from 8 ft to about 1/2 ft.

Q: 5. Will Zeiss or Voigtlander M glass work well?

A: Yes, you can use any M mount lens with the FotodioX Leica M Lens to Nikon Z-Mount Camera Pro Lens Adapter.

Q: 6. Does this adapter change the focal length of the lens you're using?

A: No lens adapter in the world changes a lens's focal length. If it is a 50mm, it will be a 50mm forever. What does happen when the sensor changes, or as in this case, a very slight extension is made by the adapter's conversion lens, is a change in field of view. In this instance, the adapter is making up for the 0.7mm difference in the two lens mounts. What will happen is a tiny widening of the field of view as compared to what you would see on an regular Exakta/Topcon camera.

Q: 7. Is there an adaptor for Leica M lenses to Nikon F mount?

A: No, M42 refers to a 42mm screw mount lens like M39 refers to a 39mm Leica screw mount lens. I am not sure what lenses use a 42mm mount, certainly not Leica.M lenses use the M bayonet mount, which is the same a Visoflex bayonet mount. You need a Leica/Leitz visoflex to Nikon F mount adapter.

Q: 8. Dear Sirs,has the adapter any cause by the focal width of the connected lense (increase of focal width)?

A: This adapter will not affect the focal length or angle of view of the lens, no. The optic in the adapter is simply there so that the lens will retain focus at infinity.

Q: 9. Will this adaptor allow the lenses to be mounted to Nikon DX bodies as well?

A: Yes, the adaptor allows the screw mount Lens to mate with the Nikon DX body without a problem, don't forget the camera will only operate in manual mode.

Q: 10. I have a special visoflex-M 90mm f2 summicron that I'd like to use this adapter with. my lens has a lip that extends out to the same distance as the mount itself. this adapter looks like it could work, but can this be confirmed for me?

A: yes it should work.
