Yes, Pentax followed up with the autofocus DA 40 Limited. (Probably the least expensive of the Limited lenses.)
It is badged as a digital-only lens (DA) but there are reports that it nicely covers the full 35mm film frame. Not sure if there are any real optical drawbacks to using the DA 40 on a film body. It sure would be an amazing mate to the Pentax MZ-S.
