Thank you! Yes, the bokeh came from the lens I'm using - a Pentacon 80/2.8, you can look it up and check out more photos made with it and all of them have this distinctive type of bokeh. It's an old G.D.R. projector lens that I've hacked to mount on my DSLR, but it's very similar to the Trioplan 100 which is easier to mount and has "niceties" like aperture blades ;) Of course, the Pentacon is much more affordable and I really love the results you can get with it when you get used to it.

You are welcome and thanks for the thorough explanation :) You got me wondering now, will I be able to mount such a lens on my Micro 4/3 camera?

Possibly, I don't know much about the micro 4/3 standard. Keep in mind that mouting something like that is never really straight-forward, but tends to be doable for all kinds of cameras. For instance, I have another projector lens that I've "salvaged" that I haven't yet made mountable. I will, but haven't gotten to it and there are always unique challenges.
