KAF3/KAF4 to E mount adapter?

Does anyone know if a KAF3 or KAF4 to E-mount adapter exists that would allow modern Pentax glass with electronic aperture and AF control to function on Sony E mount bodies?

Unfortunately I have never seen an adapter that allows for camera control of Pentax lenses for any system. I think the demand just isn't there.

That's what I thought. Saw plenty of adapters for manual control only. Nothing that would work for newer lenses without a manual aperture ring.

I believe there are some adapters with an aperture ring. However, with KAF4 lenses you're out of luck since there's no longer an aperture lever.

The demand is not there and neither is the cooperation from Sony.

Oh well. That's a shame. Would have been nice to try some of Pentax's newer glass on the Sony E-mount bodies. Thanks for the replies all.

Looks like Your stuck with the old Pentax stuff ! It really wouldn't surprise me if some third party manufacturer in China came out with one eventually.

There are adapters for use with Pentax Lenses without an aperture ring.....Just not for the KAF4 lenses that are electronic.
