That is a KAF3 lens. Perhaps you meant a KAF3 adapter? In-lens only AF, but able to control the aperture both mechanically and electronically?

A quick check suggests that that applies to all the Pentax K-mount FF lenses released over the last 3-and-a-half years, except the new D FA* 50mm f/1.4.

Is that so?

So far there are 2 KAF4 lenses, the DA 55-300 RE PLM being the other one.

The KAF3 adapter I was talking about would support both KAF3 and KAF4 lenses (but would have no AF with KAF2 and KAF - i.e. screw drive - lenses).
