The m42 lenses stop down by pushing in on the rod. The k-mount stop down by pushing sideways on a lever. I can imagine something where the widget that pushes sideway on a lever, would push on a hinged doo-hickey (pardon the technical engineering jargon) that then pushed on the rod on the lens.
Does such an m42 to k-mount adapter exist? On a related note, is what we call m42 the same as what machinists call M42? http://www.besly.com/catl/catl4124ps.htm#M42 -- The fastest way to get your question answered on the net is to post the wrong answer.
