No myth. Although I still am of the firm opinion that the better correction of spherical aberrations in the asph lenses makes their bokeh worse than that of many pre-asph equivalents. particularly the 35s and the 90 Summicron. The newer asphs - the 50/1.4, 75/2, the 21 and 24 Summiluxes are better. I still use them all, but for some purposes I prefer the older lenses.
