It's just a quirk of mine. I think when one uses the word "best" it when they are looking for the best. The "best lens" M mount new not used lens for 800 bucks might be the Cosina 35mm 1.2 whatever. But a Summilux 1.4 from Leica is hand made from real nice glass which cost some real money and cost 5 grand and represents the latest Leica cutting edge design. If best was what I was after I'd same my lunch money and get the Summilux. If "interesting, not so expensive by 6.3 times and just a tad faster I'd buy the Cosina monster. But I'd not call it "the best lens" that's ridiculous when there is an option from Leica which is gorgeous optical perfection with nothing spared. Leica gives you the option of really getting "the best". That's what interests me about it. There are such great photo companies out there. Highly competitive. Canon. Nikon. Cosina. Amazing stuff. Amazing but not "the best". I hope I'm not boring Nathan. -------------------- 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.
