I'm not saying it's not possible. but in a Pentax it might require another contact point on both body and lens I think. Still I think when Minolta added the ADI function on the Maxxum 7 it did it over the so-called data contact where the lens and camera body exchange info. So it didn't require anything new as long as both lens and body had the function. Still in a Pentax it would require that the new and older lenses had that function built in and I don't remember any Pentax zooms having a contact on the zoom ring except for the old FA lenses with the power zoom features. Maybe all their zooms have the contact and it has been unused till currently. and they wanted to use it for something since the power zoom feature has been removed from the bodies. Kent Gittings

That's why, on "portrait" mode, they'll select a large aperture when the lens is zoomed in (to blur the background behind a person) and a much smaller one when the lens is set to a wider angle (it assumes you're doing a group shot and tries to maximize your DOF). Note that I've never actually tested this myself to see if it's true; that's just what I've heard from my Pentax rep. chris - This message is from the Pentax-Discuss Mail List.
