I think I have figured the smooth bokeh out. Vivek wrote in an earlier post:
With all the adapted lenses on m4/3rds, it is, in principle, possible to focus them beyond infinity.
Going past infinity to get fuzzy images has its uniqueness (smoother).
Those who have olympus pen F lenses can mount (hold the lens firmly! it will mount but is a tad lose) them directly on m4/3rds and get past infinity.
My Pentax lens does just that. When I take bokehgraphs, I don't look at the lens barrel when I focus - I just rotate the lens until I get the effect I want. In reviewing images with this lens, I see that I have quite a few with the smooth bokeh, and others with the typical Pentax circles and lines bokeh.
Here is the original dog picture, straight out of the camera and processed as a jpeg in Lightroom

Harold Merklinger has some interesting comments on tilt/shift lense and focussing past infinity in this essay on the Luminous Landscape site.
