Greetings. While we don't test third-party products with our cameras (and are unable to properly respond regarding compatibility or limitations with them); this may be a question for Tokina.

If it works on a Pentax Super it will work on a Digital Pentax DSLR. Just how it works depends on weather it has the "A" position on the aperture dial if it does it works in auto just missing Auto Focus, if not you need to use the green button to set exposure. You also need to enable "use aperture ring" in the options on your camera body
