(2) Usually, a bokeh is hardly visible if you stop down to f 8, 11, 16, except when the in-focus subject is rather close, e.g. 1.5 to 2 meter. Let's suppose, a pic shows raindrops with sun reflections on grass/ or in a meadow on a distance between 1.5 and 3 meters. Do you, or does anybody know, whether both lenses differ just in the management of the strong contrasts (6 vs many rays of the sun's reflections), or do they differ in the management of the out-of-focus areas additionally (because of the different shape of the apertures)?
