I agree, even very well regarded lenses like the A200/4 Macro can delivery bokeh that just hoovers given the right set of circumstances. I suspect too that often the effect is exaggerated by the process of direct digital image capture particularly when citing specular reflections which may saturate the sensor leading to blooming and other edge artifacts.
