Thanks for the link. The sigma looks like a winner.
The Bokeh and 'character' is the #1 reason why I was still considering the Nikon 1.4. Second reason is that my DF had AF inconsistency with the sigma 35mm and the outer focus points.
I have similar problem with Sigma 24 on my D610. Outer AF points give me front focus when center point is properly calibrated. But it is very consistent in sense that front focus happens on the outer AF points and inconsistent in sense of amount how much it will be front focused. Also there is strong dependency on optimal AFMF value for different light colors (this can be seen with 50/1.8G too, but wideangle makes it bigger problem in real pictures). I tried another D610 and again problems with outer focus points. I tried D750 and outer focus points were consistent. I tried another D750 and it was also good. I tried friend's D3 and it was okish (slight FF with outer points, but not strong enough to care). I tried D810 and it was ok (not a proper evaluation). AFMF shift by color of light much less pronounced on both D750 and D810. So I'm now considering upgrade of my D610 because I like the lens optically.
Multi-CAM4800 just does not work well. Or maybe it needs some data in lens data firmware in camera to function properly (Sigma is out of game) or maybe it needs some additional tables in lens CPU that Sigma did not fully reverse-engineer. Also Multi-CAM4800 works poorly in low light with any lens so that is another reason to get rid of it.
Regarding bokeh, I like smooth bokeh. I wrote even this: http://jtra.cz/stuff/essays/bokeh/index.html but I still like Sigma. Bokeh in close focus is smooth enough. Bokeh in middle focus is usable. Bokeh in far focus is not great but at far focus it is too small to care about it.
That said, Nikon 24/1.8G likely has smoother background bokeh compared to Sigma. 24/1.4G is out of my price range.
