Default SLR lenses compatible with C4000?

My DH has a Pentax SLR camera, but we are stepping up to the new technology, and we're about to buy a C4000. However, we've purchased numerous lenses for his SLR over the years, and I'd like to know if they are going to be compatible (with a tube and step-up ring perhaps?) with the C4000. Any help you can give would be appreciated.

The SLR lens will not work on the C4000 model.

To expand the above answer, what you need for this type of camera are called converters, not lenses (although converters contain lenses).

A converter is something that adds on to the existing lens with the addition of a filter tube. The converter has to not only be the right diameter (can be with the aid of a step ring), but it has to be compatable with the camera.

Here's an extreme example where someone has added a Sigma VT5 5x teleconverter to their C-2100UZ:

There are not only teleconverters, but wide-angle converters, closeup, etc.

Thanks for the quick responses. I figured it would be too good to be true for those lenses to work. :?

Now hold on a second
I have succesfully attached a canon FD lens in front of my oly c3000 for macro shooting. I described the setup here:
I know that its physically possible to do it (despite what manufacturers tell ya) but i have not tried to do it for regular (read: non-macro) shooting. It may opticaly be difficult or impossible, but it has not really been tried yet. One thing i had to deal with in my setup, was a lot of glass= a lot of f-stops dropped=slow speeds. It may not work with every lens and for every application, but the theory is valid, partly tested and may be appropriate for specific uses (still life, landscape, etc).
Someone should try it for the heck of it at least. You never know
