trex1 Posted February 14, 2009 Author Share Posted February 14, 2009 <p>Hi Dan, </p> <p>That is my impression as well. The actual optics are pretty great, but the fabrication is not anywhere near up to Leitz standards.</p> Link to comment Share on other sites More sharing options...
graham_thompson1 Posted February 14, 2009 Share Posted February 14, 2009 <p>Wai -Leong. Why not take a few days off. It is obviously the wrong time of the month for you or you are a very stressed<br> person. Perhaps if you inhaled it might solve your problem. Sensible and reasonable question with helpful responses. This is what PN is or shoud be about. Having just bought an MP I find the thread interesting.<br> Carry on gentlemen.</p> Link to comment Share on other sites More sharing options...
wai_leong_lee Posted February 14, 2009 Share Posted February 14, 2009 <p>I don't have a PMS.... As for inhaling, it is escaping from reality, but doesn't really change things.</p> Link to comment Share on other sites More sharing options...
charlie lemay Posted February 14, 2009 Share Posted February 14, 2009 <p>My dad always said, "When you argue with a crazy person, no one else knows who the crazy person is." I'm sure it's a quote he heard somewhere, but he never attributed it. I advise everyone to try a HoodHat. It really will change your life.</p> Link to comment Share on other sites More sharing options...
james_cooke Posted February 14, 2009 Share Posted February 14, 2009 <p><em>"Yes, people can prefer to not search, not read reviews, etc. But is there something morally wrong to advocate self-help?"</em><br> So this is now the Leica Last Resort forum. Dont use us as your first port of call and research everywhere else first, and if you cannot find the answer then and only then trouble us with a post? Morally wrong no but pretty silly telling people not to discuss things on a discussion forum but read reviews for their answers instead. With that logic no forums like this would exist!</p> Link to comment Share on other sites More sharing options...

michael_markey Posted February 15, 2009 Share Posted February 15, 2009 <p>Really good thread. I bought an M3 and paired it with the Nockton SC 40m. Recently bought a Leica 90 2.8 Elmarit m.The point is ,I am happy to mix and match depending on price,quality and the amount of usage that I will put the lense to. The helpful opinion which has always been the hallmark of this forum has often proved invaluable to me in making these decisions. Please continue to provide it. </p> Link to comment Share on other sites More sharing options...
jiajun_yang Posted February 15, 2009 Share Posted February 15, 2009 <p>It s no reason for argument or even fighting.We just share our experience of the lens and that s it.<br> I currently use the nokton 35mm/1.4 and I found it really amazing.But maybe I just be a little sensitive.I think the color what this lens brings out is a bit too much.<br> So if money is not the biggest prob,i will prefer leica lens.<br> ^^</p> Link to comment Share on other sites More sharing options...

thomasw Posted February 18, 2009 Share Posted February 18, 2009 <p>Stuart: I think Leica now have a comparable lens to the zm 18/4, their 18/3,8 should be very interesting.</p> <p>OP: I had a ZM 50/2 and thought it a fine as an all-round lens, but I traded it for a mandler-designed 50/1,4 lux. What it lacked was low-light applicability and a distinctive look, a character flaw or something that said 'this is That' lens. This is just my take, of course. I have a thing for lenses that might be 'flawed' in a certain sense but yet have a distinctive rendering. I think the sonnar zm 50/1,5 is a more interesting lens in terms of its rendering.</p> Link to comment Share on other sites More sharing options...
roland_r Posted February 19, 2009 Share Posted February 19, 2009 <p>Hi Darius,<br> congrats on a nice combo. IMO, for all practical purposes, the ZM Planar, modern Summicron, and M-Hexanon 50/2 are pretty much equivalent. Of course there are some minor differences when it comes to flare, and high magnification resolution, but not much.<br> With respect to signature, it gets more interesting when you consider other specifications. For example, the M-Elmar 50/2.8, ZM 50/1.5 and Summilux pre-asph v3 produce beautiful images, all three in very different ways. The M-Elmar, BTW, is quite affordable.<br> Some Leica prices are partially justified in the design, not only in the quality. For example, the modern Leica 50/1.4 Asph includes aspherical, floating AND apo elements, none of which are featured by Japan-made ZM lenses.<br> In general, I don't think Cosina Voigtlaender vs. ZM quality is any different. There are better and not so good lenses. For example, the CV 28/3.5 and 35/1.4 that I use often are very high in build quality. One Nokton I had "wobbled" (easy to fix), but similar issues have been reported on Planars and Biogons. In general I feel it's great that there are so many lenses of different specifications to choose from.<br> I would be interested in more information about the manufacturing process of the two lens lines at Cosina, and other details; for example, how are CV aspherical surfaces made, compared to Leica for instance. Haven't found anything yet, however.<br> Regarding build quality, if you like chrome and brass, nothing currently available beats the built quality of Leica, Nikon LTM or Canon LTM lens of the 60s though :)<br> Best,<br> Roland.</p> Link to comment Share on other sites More sharing options...
35mmdelux Posted July 17, 2009 Share Posted July 17, 2009 <p>ok, did we decide the ZM 50/2.0 is ok?</p> Link to comment Share on other sites More sharing options...
shadowleaves Posted August 2, 2009 Share Posted August 2, 2009 <p>did any one ever perform a side-by-side test of ZM 50/2 and Summicron-M 50/2, shooting the same scene at the same time on Provia or something similar? that could be really interesting to see...</p> Link to comment Share on other sites More sharing options...
