(3) DO elements create onion ring bokeh, but that's ok because bokeh is totally unimportant in macro shooting.

Neuro, I probably miss the meaning of the ::) smiley

All three of those points were facetious.  I often forget my </sarcasm> tags...   :)
EOS 1D X, EOS M, and lots of lenses

PBD - that looks like a scene that should be in the movie Dazed and Confused :D

I see what you mean about the onion skin look.   It's very evident in that picture.
What I do today is important because I am exchanging a day of my life for it.

I've been hoping for a 180 II, but was hoping for f/2.8, 9 bladed diaphragm, and the like, not DO.  Let's hope this is just a defensive patent.

Happy with F4, 9 bladed diaphragm and Tilt functionality to increase DOF a bit
