An 31mm lens on APS-C (="48mm f/2.5") is not really an obvious candidate for this.

f1.8 makes it more of an obvious candidate though... Even at f2.7 (not f2.5) equivalent you still can get a lot of blur in images, and then bokeh assessment is not so strange.
What I notice from images taken with this lens is very nice bokeh with relatively up close scenes, like here:

but rather unattractive bokeh when the background is further away:

Not double edged nissen bokeh horror, but a kind of "blooming" in the bokeh which I have also noticed with my Canon EF 35mm f2 (but to a lesser extent!).
