I use GH2 + Helios 44-7 58mm f2 + 35-nap2-3M (35-nap2-3M) 80-140 f1.8 2x My problem is that I have vertical and horizontal bokeh. Foreground blur is vertical and background blur horizontal, so changing focus means bokeh goes from horizontal to vertical and vertical to horizontal. It's strange behaviour. Do you know why does it happen? See test from 3:30:
