New to me old lens...

I bought a RainbowS8mm 1:1.4 this afternoon in a thrift store. It has a plain screw mount. Someone has posted pics of the same lens here(Rainbow S8mm Lens Photos by expresscash | Photobucket). Mine came in the same white box and at some point was selling for $79.99. Any idea what it's from and any chance I can buy an adapter and use it on my Q?

Thanks,

Stevi

It may be a C mount cinema lens, in which case if you can find a C to Pentax Q adapter you should be able to use it. I believe that the C mount is 1 inch diameter and 32 threads per inch.
