Unsurprisingly the worst of the gang but still decent for a 20mm lens.
FWIW, I've added a sunstars chapter and another bokeh sample to the other two reviews as well.

It's a fair lens, in the end, as you stated in the price/performance evaluation. I see that you confirm that at ƒ/4 the light spots are "almost" circular, but not as circular as the advertising promised. It's probably the single thing that I was disappointed by.
For what concerns distortion and relatead loss of sharpness, it's a lesser problem if a) you use it on a APS-C camera b) you're doing macro (which means you most likely want blurred things around the subject) and c) you use a partial correction profile. With the last point I mean that you can reduce the distortion correction in post-processing if you are not shooting architecture (c-plan with this lens for me).
