Kenko Pinhole lens 02 on Nikon M2 mount?

[Railphotog]

A local online sales site has a "Nikon F50 with a Kenko Pinhole lens 02, Nikon M2 mount" for sale. Looking for info on the Kenko. I did a Google search, and didn't come up with a review that mentioned how the pinhole lens performed. Years ago I had a lens cap with a pinhole aperture in stainless steel, and it had a small "co lens" in front which aided the sharpness. It worked pretty good on my film camera, sold it off when I switched to digital.

I'm wondering if this Kenko pinhole produces relatively sharp photos, or fuzzy ones? I'd like to use it in my model railroad photography.

Secondly, will the Nikon M2 mount that comes with it work and fit on my Nikon D80?

Thank you!
