Astro-photographers will be looking here, wide open is where they will scrutinize, it does well, but what about it's coma? just been shooting stars with the AF20mm F2.8D (no laughing please) hence the subject of coma, the Nikon looks like the vapour trail from supersonic aircraft at the point of the sound barrier.
The performance of this lens will be affected by it's parameters here!

I did a astroshot yesterday. Not optimal though - some star trails are visible - albeit nice composition I think ;-)

I added some samples showing the bokeh and flare.
While you can't really expect a nice bokeh from a wide angle lens, the flare handling is worse than average.
The field curvature is also heavier than indicated by the lab tests. I would recommend f/11 to overcome it really.

The sun stars are cool, more organic looking than the very regular sunstars you get on something like to 16-35 2.8.

Kevin (Laowa) told me that they are not seeing the field curvature in some of their samples.
He'll provide sample images.
They'll also investigate the flare issue.
