The Adapter for Nikon F Mount Lenses to Pentax Q Mount Mirrorless Cameras from FotodioX allows a Nikon F Mount lens to attach to a Pentax Q-series camera body. Adapting a larger format lens to a smaller format sensor provides optical as well as practical advantages. The smaller image field helps minimize the effects of lens distortion and aberration by using the center or "sweet spot" of the larger lens' image circle, thus providing edge-to-edge sharpness.

Although the lens will fit physically, automatic diaphragm, auto-focusing, or other electronic functions will not operate correctly while using this adapter. Manual or aperture priority mode must be used when this adapter is attached. Its all-metal design and polished surface provide smooth mounting and long lasting performance.

Q: 1. Does anybody know if you can use the auto focus 645 pentax lens to be electronically connected via an adapter to a nikon D800 SLR? I will be grateful for any help. Thanks, John Dufton

A: There is no electronic connectivity between Pentax AF lenses and a Nikon digital body with this adapter. Manual focus and manual exposure control. If you chose this route, you're going old-school so be prepared to miss a few shots unless you're stopped down for a wider DOF.

Q: 2. Does this adapter work with wide apartures like F1.2 or f1.4?

A: Yes. Is make sure to match the solid white dot to the solid red dot. This is allows you to set the aperture manually.. You may have to stop down a bit it's a bit the compensate for vignetting. Note the lens is purely manual in this this configuration and none of the auto features will work.

Q: 3. What is the function of the movable silver ring on the adapter?

A: This FotodioX Pentax K Lens to Nikon Z-Mount Camera Pro Lens Adapter is designed for lenses that do not have a manual aperture control ring, such as the newer Pentax K AF lenses. This adapter has an aperture control dial built into it which will allow you to open and close the lens manually. The silver ring is for controlling the aperture.

Q: 4. would the medium format pentax 6x7 lenses fit this adapter and work on nikon digital (d610)and 35mm(nikon f100) film bodies?

A: There is, I believe, another Fotodiox adapter specifically for Pentax 6X7 lenses to Nikon F-mount. Pentax 6X7 lenses are much larger.

Q: 5. Hi Does this adapter affects image quality?

A: Hi--there are no optical elements in this adapter, so it will not affect image quality at all.

Q: 6. no change on focal length?

A: No, the focal length remains constant.

Q: 7. Does it also work with Pentax PK mount lenses?

A: Wikipedia says PK is an abbreviation for Pentax K so it should.

Q: 8. 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: 9. does this fit a nikon d850 camera?

A: Yes, it does.

Q: 10. 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!
