The Law of Diminishing Returns states that you
pay 95% more to close from 90% to 95%
perfection. Optical quality mandates quality
prices. There are several Japanese firms --
Asahi pops to mind -- which routinely offer goods
equal to those of Zeiss but, then, they cost like
Zeiss. It is a matter of simple economics.
