What's your "Bokeh Monster"

For m4/3 system and for 2/3 to full body portraits I would prefer 85mm lens (170mm FF equivalent). I own USSR age Jupiter-9 85mm f2.0 lens. I have rangefinder version with M39 Leica screw mount. It is Sonnar Zeiss copy and thanks to 10 aperture blades has very pleasant bokeh. See samples: http://natalispalette.jimdo.com/photo/jupiter-9-85mm-f2-0-lens/

I also bought famous Minolta MD 85mm f2.0 but had no time to test it…
