Guest Rollei.Leica.Brujo Posted October 12, 2013 Share #1 Â Posted October 12, 2013 Advertisement (gone after registration) Hello, Everyone, and thank you for reading my post. I was wondering if the Leica Summarit 50mm 1.5 L39, could be used on the Leica M9, or will it need to be adapted? If so, how do I go about find this adapter, and which size would it be? Thank you! -Americo Link to post Share on other sites More sharing options...
Advertisement Posted October 12, 2013 Posted October 12, 2013 Hi Guest Rollei.Leica.Brujo, Take a look here Leica Summarit 50mm 1.5 L39.... I'm sure you'll find what you were looking for!
menos I M6 Posted October 12, 2013 Share #2 Â Posted October 12, 2013 Hey and welcome! You can use your Summarit L39 on a Leica M9 - it is a great lens! Â You simply need a L39 to M adapter ring (often called LTM adapter). Â The most reliable source is Japanese Voigtlander, which provide very high quality and reliable measurements (I use them now exclusively on all my LTM lenses after experimenting with vintage Leitz and many cheaply made adapters). Â Adapters: LTM to M Â You can use the newer type II adapter from them, both fit the Summarit L39. Link to post Share on other sites More sharing options...
Jon Pop Posted October 13, 2013 Share #3 Â Posted October 13, 2013 Voigtlander makes the best adapter for sure...you'll want the "Type II" adapter which doesn't have a cutaway (compare them and you'll see what I mean). The reason is that the Type 1 leaves the entire LED section for the 6-bit code reader exposed. I don't know if that's relevant or not, if an uncovered 6-bit code reader reads some kind of weird signals or not (other forum members can correct me), but I did get some weird rainbow patches on my images when using the Type 1 and a 50mm Summarit 1.5; they went away with the Type 2. Â Have fun....an interesting lens with a definite character that some love and others hate. Crazy Xenon bokeh, very swirly/van gogh. Cool! Link to post Share on other sites More sharing options...
jaques Posted October 13, 2013 Share #4 Â Posted October 13, 2013 Not sure- but my camera tech says that the Voiglander rings can be a little too fat, so focus is off- and that the original Leica ones are often a better match? Link to post Share on other sites More sharing options...

Â Jaques, the issue with original Leitz adapter rings is, that they have been manufactured over such a wide span of time and current available second hand adapter rings are in such wide spread condition from like new to completely unusable, that I have stopped buying them. Â Add that nowadays these original Leitz adapter rings are traded at highly inflated prices, mostly exceeding the cost for highest grade new rings, as every seller tries to make a killing as of the original Leica provenance despite often questionable conditions of the item. Â I found the modern Cosina Voigtlander rings extremely reliable (I must have something like ~20 or more of them) and fully interchangeable. The Leitz rings, available on the second hand market do have a sample variation similar to the cheapest adapters, available on eBay - variations due to potential changes over the years of manufacturing and mostly issues with the rings themselves - a slight bend of the flange, very difficult to spot will completely throw of the calibration of a critical lens. Â When calibrating critical fast lenses for a Leica M, the smallest fraction of a millimetre has a very large impact on accurate focussing. A tiny dent of a adapter ring, that lifts the adapted lens just 0.01mm away from the camera will already result in mis-focussing. Â Sometimes, I go through the struggle of re-conditioning misaligned adapter rings, but at the handy price a brand new Voigtlander ring is readily available, it is hardly worth the trouble (in combination with the very high prices).

tobey bilek Posted October 14, 2013 Share #6 Â Posted October 14, 2013 I have measured CV rings with original Leitz in good condition and they are exactly the same. You need a micrometer. Â The cut out is required for lenses with an infinity lock or you need to remove the lock. You need the metal there to code the ring if you wish to code it. There is not much reason to code a 50 1.5. Â The flanges that are too fat are the replacement bayonet ones from Jinfinance. I grind them down to match the individual thickness of the bayonet removed. Measure with micrometer. Some work fine, others I had to remove up to .001 and .001 does make a difference. Â I have bought two screw to bayonet with pits milled for coding and they worked fine, but I never measured them. An acquaintance bought one and used it in place of a Leitz original so it could be coded and focus improved so there is some variation there. Â Avoid cheapos for on Ebay.

Jon Pop Posted October 15, 2013 Share #7 Â Posted October 15, 2013 Advertisement (gone after registration) Just a quick additional bit of info between Type 1 and Type 2 Voigtlander adapters and the Summarit 50 1.5....while it's true that the Type 1 is for lenses with infinity locks (and the 50 1.5 has an infinity lock) the focus tab is a bit further away and so the Type 2 works fine. Type 1 is probably mandatory for older LTM lenses where the focus button/infinity lock sits very close to the body once mounted. Â But I would definitely in any case avoid the cheap eBay $10 adapters... unless you have access to grinding machines and precision measuring tools...

250swb Posted October 15, 2013 Share #8 Â Posted October 15, 2013 I've always found the cheap $10 Ebay specials to be pretty good, definitely worth trying before throwing money at the problem unnecessarily. Â Steve Link to post Share on other sites More sharing options...
Guest Rollei.Leica.Brujo Posted October 17, 2013 Share #9  Posted October 17, 2013 Hello, Everyone, and thank you for reading my post.

Thank you! -Americo   Guten Tag! Thank you all who have answered, and committed your time, doing so! I apologize for the delay in replying, and giving proper thanks! I am however no longer in need of advice, because I have decided against the Leica M9 route as hard as it was! I opted instead to stick with the DSLR by means of Canon 6D via Canon EF 85mm 1.2 MK II L to utilized the legendary bokeh it offers, plus its light anemic quenching need! I have received this fine lens, from the seller known in Leica community, Kohs Camera Inc., however, rather than waste his time with returns, based on my err, I have decided to attempt its sell, on a popular forum, fredmiranda, and I may turn to ebay soon, maybe! Again, I appreciate your fantastic advice given, and time wasted doing so! I will keep in touch with this fantastic forum, and maybe, just maybe one day, i can join for keeps! I would love to pair this fine German engineering, with my Rollei 6008 German descendent! Bis bald!    $(KGrHqV,!lcFI3wedvd,BSTyQ8g8mQ~~60_57 by aRolleiBrujo, on Flickr  $(KGrHqN,!qsFI+O7iEKgBSTyQyyw,!~~60_57 by aRolleiBrujo, on Flickr   FS: Bokeh Leica Summarit 50mm 1.5 L39 Screw Mount Lens w/Cap - FM Forums Link to post Share on other sites More sharing options...
