I read a post in the past about fitting Nikon lenses to Pentax digital cameras. I never tried this but after reading the post I thought I would give it a shot.
Here's what I found:
1. It does work
2. Non AI also work
3. I wouldnt suggest doing this in the field. (Lenses can fall off easily)
Perhaps I'll snap a few quick jpegs this weekend and post them.
No adaptor needed folks, it's quite a find for me.  |

Do you think it works vica versa? Pentax Lenses can be mounted on Nikon without adapter? Minor shaving of the mount no problem... |

Nikon has perhaps longest register distance form all 35mm SLR , you can't mount any other type of 35mm SLR lens what is works perfectly on Nikon body.

Attila,
Your confusing me a bit.
You stated that the Nikon lenses would work on a Pentax just like M42 lenses on Nikon cameras.
M42's on Nikon cameras will not have infintiy focus capabllity without the extra glass element.
The Nikon lenses perform with no such adaptor needed on the Pentax. Infinty and closup capabilities are very usable.
So, I was a bit confused by your statement. |

Pentax lenses not work on Nikon body perfectly, because they have shorter register distance than Nikon.
This is same case than M42 lenses on Nikon body.

O.K Attila, I see what you were saying.
The biggest surprise was that I could mount them and still use the camera functions perfect. AI and Non-AI. |

Attila,
They semi-lock into place. I can tilt my camera all the way forward and the lens will stay mounted, but a slight jar or quick movement may dislodge them. I would suggest using them with care. |

It's great, isn't it? 
I had a few Nikon fit that have a new lease of life on the K10D. They do fit quite snugly, and if I wanted to, I could drill a small locating hole on the mount for the Pentax locking pin, but I don't think I'll bother.

Are there Nikon mounts that do and do not work??

You have to remove the tiny stop screw at the side of the lens mount, then it will fit on and turn about half an inch. It won't lock, but slightly jams in place enough to use. On an AIS lens, you might have to remove the secondary smaller aperture indicator quadrant, as it fouls the mounting ring/body.

My ais lenses fit fine, I took a shot with my Tamron 24mm ais. No problem. I love the fact that my Non-Ai lenses work also. |

This is absolutely incorrect. I posted shots taken with the Tamron AIS and the Nikon AI. No problems. |
