Bokeh has nothing to do with sharpness: two lenses that depict objects in focus equally sharply can have a completely different blur pattern, the subjective artistic merits of which are described by the term bokeh.

A novice photographer is looking for a subject to shoot, while an experienced one is hunting for light.
