I like the bokeh as well, I think the issue is the amount of bokeh in comparison to the subject. The bokeh appears to comprise 80% of the whole image, which tends to dominate the subject, the child. The bokeh is soft but it appears the background is being seen through a window?
I have a 50/1.4 summilux (pre asph., E43 version) and it is not 3 times better than the 45/2 planar.........only 2.75 times better 😉
