I doubt the differences between the legendary Leitz 75 Summilux and the just not quite out Cosina 75 for M come down to a minor manner of convenience or opportunity as a lens choice. They have much more NOT in common than in common - Despite having the same oddish focal length. I think the Leica/Leitz people deserve more credit that that. Perhaps some reading on the history of the Summilux 75. Perhaps in Erwin's book. They sank a lot into that lens. What is going behind a Summilux 75 in terms of glass choices, design, manufacturing tolerances, and build is many times the Cosina Voigtl?nder 75 mm f/1.8 in M mount. The 75 Summilux we'll never see the like of again its a majestic archaic monster. In comparison the Cosina is here today gone tomorrow toy. And which is why you'd pay a fraction of the money for one. The 75 Summilux we'll never see the like of again. I don't care who thinks the first out images look similar in some way we'll see what Erwin says about it. -------------------- Mark William Rabiner Photography mark at rabinergroup.com > From: Marty Deveney <benedenia at gmail.com> > Reply-To: Leica Users Group <lug at leica-users.org> > Date: Mon, 23 Aug 2010 13:22:09 +0930 > To: Leica Users Group <lug at leica-users.org> > Subject: Re: [Leica] new 75mm M lens > > And the main engineering solution to the near-far correction problem > is a floating element, which Cosina is not set up to manufacture.
