K-01 and Pre-AI Nikon lenses

I heard about Nikon lenses force fitting on the K-mount, and I decided to do some personal testing with some old Nikon lenses on the brick.

MF Nikon lenses in possession:
Nikkor-S 50mm f1.4 (pre-ai)
Zoom-Nikkor-C 43-86mm f3.5 (pre-ai)
Micro-Nikkor-P 55mm f3.5 (pre-ai)
Nikon Nikkor 28mm f3.5 (ai)
Nikon Series E 50mm f1.8

After toying around and freaking out that I was going to ruin the mount, I learned the pre-AI lens fit really snugly with no worry of falling off.

BUT!! The AI lenses (and the series E) don't fit well. The AI aperture ring doesn't surround the outer part of the mount.:fedup: Now, I'm too freaked out for the lens and the mount to try to squash the AI lenses on again.

The K-01 with a pre-ai Nikkor lens (taken with a camera phone :o):

Test shots (50mm f1.4):

The K-01 is my first Pentax camera. I don't have any lenses except for the 40mm XS, so I'm really happy I can use my fast Nikkor f1.4 until I can round out my Pentax lens collection. :D
