Hi,
The Nikon manual lenses fit the K-mount when properly positioned. You must make sure that the light baffle doesn't protrude more then 8.5mm into the body past the mount. Insert the lens with the index dot at about the 6 o'clock position. Seat gently. Take using the camera, since the lock pin isn't seated. Here is a photo of my 35/2 mounted on my K100DS.
