I would have bought it for $80 just for the birds and squirrels.

With K mount lenses you only have to activate 'set aperure ring' the other setting 'FI with S mount' is for screw mount lenses.

For any K mount lenses to work, the electrical contacts on the camera need to be shorted out, this normally happens via the steel plate of the Pentax K mount.

But as many old K mount Cosina lenses have a black teflon-like anti-electric coating and I suspect the thread authors lens has one of these. You can slip a piece of tin foil between the lens and the camera but this would be awkward and need to be done every time you use the lens or do what I do and make it permanent. I rub the coating off in the appropriate place and reveal the metal underneath. Once you've done this Cosina lenses will behave exactly like a Pentax assuming of course it has a correctly functioning aperture lever

That's correct, for some reason, I thought the OP was using a screw mount lens.

I believe from the pics the OP attached, he is attaching to a K10D as well, so he'll never find the 'FI with S mount' option
