I don't see any Onion Bokeh? Do you mean just bokeh.
Actually that's pretty much unavoidable. it has nothing to do with the lens.
bokeh is produced when your focus item distance to the lens and the background ratio is.. near:far
it can be reduced by using small aperture but in the case of macro, the focus area is very near to the lens.
even with DSLR where you can adjust the aperture to really small aperture, you will still get bokeh with macro.
Onion Bokeh this bokeh.
Tamron 24-70mm has Onion Bokeh.
The Nikon doesn't.
They call it Onion Bokeh because it looks like an Onion being sliced across in half.

Now look at the Bokeh on the Z1.

But then again, if the guy was using some Macro add-on clip, the Onion Bokeh could have resulted from using that add-on.
