The dilemma for me has been this.
For the J3, I find that the more funky bokeh and harshly clipped OOF highlights on the edges go away at f2.
But in that case, I might as well buy/use my J8.
In fact, I find the same with the Nikkor 50/1.4 ltm (another sonnar pushed to f1.4).
Harsh and tendency to more funky bokeh until stopped down.
It seems that the Sonnar design gets better in the bokeh the longer the lens? (ie. 58, 85, 135, 180mm)
Nice images shared so far.
I do love my J3 very much (warts and all)
