It means the Red, Blue and Green light waves focus at the same place. Second, ASPH stands for Aspherically manufactured lens elements. One has nothing to do with the other. They both make the lens technically superior. They correct different lens aberrations. Stating that you prefer or hate one and not the other is meaningless. Wait for the glass to be available then try it out. Remember, buy great glass. It keeps Leica alive for us all. Frank Filippone red735i@earthlink.net
