Bokeh is a term, originally from Japanese (ζγ-to blur; or γΌγ), that has come to mean the subjective aesthetic quality of the out of focus area of an image. Two key terms in this definition are SUBJECTIVE and IMAGE. One cannot measure bokeh, as it is something that may be pleasing to one person and not another. Bokeh is a property of IMAGES, not a property of LENSES..example:-
