How to Use a Nikon manual lens on a Pentax DSLR body

The main point of this article is that a Nikon manual lens can be used on a Pentax DSLR body directly without an adapter.

Some people said the lens mount must be modified or take an adapter to mount a Nikon F-mount AI or Non-AI lens onto a Pentax DSLR body. I don't agree with these opinions. Please look at the picture on the website so that you will learn how to mount a Nikon AI or Non-AI F-mount lens onto a Pentax DSLR body. I also believe that a Nikon F-mount AIS lens can also work in the same ways that the pictures shown.

AI-type Nikon F-mount lenses are just ok on a Pentax k-mount body. You even don't need to modify the lens's mount. You just need to turn the lens a little bit to left or right (depends on which side you are looking at the camera and the lens. After it is mounted and when you hold the camera to take a picture, the aperture center mark should be tilted to left) and try to find a best position to connect them. The connection is tight enough for most prime lenses as long as the weight is moderate, so that you are free to change aperture and focus. I am not sure whether the connection is secure or not if a lens is too weight.

With my experience, Both Non-AI and AI Nikon lenses can work on a Pentax body directly without an adapter. The focusing distance is exactly as the distance marks on the AI lenses, and a little bit change on the non-AI lenses but focusing on infinite is still ok.

However, you must be very careful when you try to mount a Nikon lens onto a Pentax body. "Tightened enough" is enough. It should not be over tightened, otherwise it may hurt your camera body's mount.
