Sorry David, but I've got to disagree with you. Japanese companies design
and manufacture lenses for specific parts (amateur/pro) of the market. They 
decide what kind of lens to make and then set a price for that lens. Leica 
reverses this, they make a lens and after that they calculate the price. 
Japanese companies work this way because they have compete with each other. 
Erwin Puts, a Dutch Leica specialist put it this way:

Nikon competes with Canon, Minolta competes with Pentax, but Leica competes 
with Leica.
