Fa 50 f1.4 is like most of the limited bokeh, foreground better than background blurr. it happens to Nokton as well, just a little less harsh.

Green background bokeh are easy to render for most 50mm. So it is not surprising that the bokeh turns out not too badly.

Oh, yes. Da* 55 does have a high standard to meet with that kind of pricing. I just pray that pentax does not use the same skeletal optical design in the line of 50mm series from its history.
