arild_reppen1 Posted January 24, 2001 Share Posted January 24, 2001 Does anyone have any experience with the collapsible 50/2.8 for Leica M? I have read it's low contrast? Is it worth bying (for bringing my M6 everywhere)? Link to comment Share on other sites More sharing options...
andrew_schank Posted January 24, 2001 Share Posted January 24, 2001 The fact that you have to pull it in and out all the time is kind of a pain. Plus the regular 50mm f2.0 Summicron is just such an incredable lens. If you want a very compact lens to bring the M6 everywhere, how about the last series 35mm f2.0 Summicron. It is very small and short and a great lens all arouind. Link to comment Share on other sites More sharing options...
wilhelm Posted January 24, 2001 Share Posted January 24, 2001 The 50mm Elmar f:2.8 is actually the same weight, and virtually the same size as the collapsible Summicron, which is a much better lens. The f:3.5 M is the same. The f:3.5 LST however, is much smaller and lighter, even with the bayonet adapter, and the very late ones are optically as good as the f:2.8 (near as I can tell). Also, a black M- 6 with a LST Elmar has to be the prettiest camera since the Leica Standard with a black-rim Summar. Link to comment Share on other sites More sharing options...
Robin Smith Posted January 24, 2001 Share Posted January 24, 2001 The current Elmar-M is, I understand, considerably better than the original Elmars. Modern glass and coatings. But I tend to agree with Andrew - unless you absolutely must collapse the lens to fit in a case then I would get the 50 Summicron. However, the original collapsible Elmar is a classic old Leica lens and you might well like the look of the photos taken with it.

albert_smith Posted January 24, 2001 Share Posted January 24, 2001 This question came up last month. You can read those reponses at the link below. <p> I believe the advantage of the physical size is only an advantage during transporting of the camera in a "non-shooting ready" condition. If you are actually in the process, or ready for the process of shooting, the lens would be extended, and hood installed, so this lens and a Summicron would be about the same size. <p> My personal choise for a minimum sized outfit would be the M6 and the last pre-ASPH 35mm Summicron, which without the hood is only a tiny bit bigger than the collapsible 50, and an excellant performer. <p> http://greenspun.com/bboard/q-and-a-fetch-msg.tcl?msg_id=004HpW Link to comment Share on other sites More sharing options...
jay_. Posted January 24, 2001 Share Posted January 24, 2001 The current Elmar is a nice lens, but not all that compact. With a filter and hood on it, even collapsed it isn't much smaller than the Summicron which is a stop faster and optically superior. To transport your Leica in your pockets, just remove the Summicron to another pocket, re-attach it before shooting. Takes not much more time than un-collapsing the Elmar. I have enjoyed my Tri-Elmar, it isn't too compact, but in comparison to 3 lenses (28, 35 and 50) it takes up less space and is faster in shooting.

john_chan2 Posted January 24, 2001 Share Posted January 24, 2001 I'd stick with the 50 mm Summicron. Its faster, its optically superior, and its cheaper. Paying more money for less speed and less optical performance is beyond my comprehension. Unless you're buying the lens for nostalgia. <p> BTW: I second the vote for the last pre-ASPH 35 mm Summicron as the lens of choice for a standard. Its small, its light and the performance is astounding and in some respects even better than its ASPH successor. The Elmar is a museum lens IMHO.

arild_reppen1 Posted January 25, 2001 Author Share Posted January 25, 2001 Thanks all for your responses to my question. I think I'll stick to my 35/2.0 Summicron, which is my preferred lens today. Link to comment Share on other sites More sharing options...
xav Posted January 25, 2001 Share Posted January 25, 2001 My main lens is a 35 Asph Summicron. I also have a latest 50 2.8 Elmar (it came with the camera). I use from time to time and got several beautiful shots: The lens is very good, although probably not as good as the 50 cron.I carry my camera with the 35 cron everywhere. I also have often the collapsed Elmar in one of my pocket... It helped me a few times when I could not get close enough to my subject to eliminate unwanted surroundings visible with the 35 mm. <p> To be honest, I could live without the Elmar, but its small size is convenient... <p> Xavier Link to comment Share on other sites More sharing options...

frank_horn Posted September 15, 2001 Share Posted September 15, 2001 I've shot with the 50 Elmar-M on my M4-P. Can't see any difference in picture quality between it and 50mm Summicron. If you only carry one lens, a 50 is handier than the 35. But the 35 Summicron is a great lens. Makes M4-P pocketable. A collapsible lens, to my mind, is not as user-friendly as the rigid, especially with built-in hood of latter. For one lens only, I like the idea of a 75 Elmarit-M! You can usually get farther away, but hard to get closer, in many cases. Leica ought to make such a lens. Link to comment Share on other sites More sharing options...
raymond_tai Posted September 17, 2001 Share Posted September 17, 2001 The latest 50/2.8 Elmar is a very sharp and high contrast. The 50mm Summicron probably makes more sense if you are going to have one 50mm since the extra speed is more usable however there is little performance difference between the two and the Elmar may be better if you love contrast. I myself prefer the Summilux. Link to comment Share on other sites More sharing options...
