Bokeh: Good vs. Bad?

[PavelR]

The lens I own and like the most for the bokeh is 200/2 (see the attached images).
There are also other which I like too: 120-300/2.8S, 85/1.2 II, 50/1.4A, 300/2.8.
(I do not own 400/2.8, but the bokeh is superb...)

For my tastes some of those backgrounds look good, and some of them are distracting and would be better a little less blurry.

My rather uneducated comment would be that the photographer still has to be very careful about background choices irrespective of lens used and its bokeh characteristic. Just because objects are not clearly identifiable doesn't mean they can't be producing undesirable visual effects. Easier said than done, of course and some subjects can't or won't cooperate.
