RE: [Leica] Critical test reports by CDI

["B. D. Colen" <BDColen@earthlink.net>]

Naaah - Don't get the shorts knoted. But...I contend that the most
interesting thing about those tests is the comments regarding price and
value....And there I think they really do have a point. It's one thing for a
lens to cost a bit more because it's a bit better, but when it costs several
times what a lens that is only very slightly inferior costs, the market
begins to shrink quite radically...
