RE: [Leica] Re : Summicron 50

["Bergman, Mark A." <mabergm@nppd.com>]

I got to look at this lens this weekend in Kansas City (the Cosina Nokton 50
1.5) and was told that the lens is not rangefinder coupled.  The clerk
wasn't terribly knowledgeable but I could not see how it would be.  Is it
rangefinder coupled?  Anybody using it?  I have a 50 Summicron now and have
been toying with the idea of splurging for the Summulux for awhile now (at
least 3 or 4 years anyway).  I just can't convince myself that I really need
the extra stop.

And the fact that the formulation of the Summilux M predates the Presidency
of JFK is why Erwin Putts' testing showed the $350 "voigtlander" Cosina
Nokton 50 1.5 to be at least marginally superior to the Leica lens....and
the Nokton has at least one aspherical element.....for $350....which is,
what, 1/5th the price of the Summilux?
