No there are no power contacts in the *ist-D or Ds, but that's not why it's crippled. It's crippled because
there's no aperture simulator lever. Power zoom hasn't been fully supported since the z/pz-1p.

AFAIK there's no more electrical contact from the body to the lense that
could provide power for stabilisation. This looks like an early decision
against IS within the lense.


Actually, in KAF3 patent filed by Pentax a few years ago power zoom contacts
were utilised as source of power needed by I.S. KAF3 according to technical
specifications available in patent is ready for both - I.S. and in-lens AF
motors, but it hasn't apeared in any of Pentax products so far...



What's the current mount?

http://kmp.bdimitrov.de/bodies/digital/star_ist_d.html is outdated and does
not list the Ds yet, but names 'crippled' KAF2 for the *ist D.

http://kmp.bdimitrov.de/technology/K-mount/Kaf2.html  shows the Power
Zoom contacts inside KAF2. Are they still around for *ist D / *ist Ds?

http://kmp.bdimitrov.de/bodies/digital/star_ist_D.jpg may be a
pre-production image. However, you can see very well that there are no more
Power Zoom contacts.

IS and in-lens-AF would not work with *ist D/*ist Ds - would it?

Thanks,
Martin
