Do SLR Pentax lenses fit on the digital SLR

I'm thinking about getting a digital SLR. I have a regular Pentax SLR and a number of lenses and filters. Will they work with a digital SLR by Pentax or do I need to start over?

Hi

You can use any bayonet (K mount) lens on the Pentax digitals, but performance and features will vary widely with the series of lens. In other words, not all functions may be available, such as autofocus, metering and so on, but you can still take a picture with any K mount lens manually.
