FYI I took dayrlgo's advice and purchased a version 1 (pre ASPH) 50 lux to get the Leica glow... I cannot wait to receive it and and try it on my newly acquired Monochrom. Once bitten by the appreciation of older glass it adds to the joy of photography. Stan Tamarkin, if you call him he could very well have one or more 35/1.4, the lenses listed on his website are fewer than stocked. He’s trustworthy. You will love the 50 ver 1, the softness wide open is beautiful. They are not seen often, occasionally I’ll spot one online. Link to post Share on other sites More sharing options...

Sorry, Steven, I've never owned the v1 35/1.4 Summilux pre-asph so I have nothing to compare. None of recognised experts Erwin Puts, Dennis Laney, Gianni Rogliatti, the Hove Leica Pocket Book or Ghester Sartorius mention two separate versions but clearly there were two versions because one (the v1) has the steel rim and takes the OLLUX hood but the other doesn't. They both share the same serial numbers so the conclusion must be that the differences between the version 1 and 2 are purely cosmetic and the optical computation and design are the same, which means that their images will be the same.

Ernstk Posted January 24, 2021 Share #24 Posted January 24, 2021 There has been much discussion on the 35 'Lux pre asph in the last few days, much of it generated by Steven. As has been quoted on more than one occasion, the mechanical and fundamental optical properties of the lens are unchanged between versions 1 and 2, apart from the external cosmetics (i.e. 'steel rim'). However, at serial number 2166702, in version 2's production, 3 of the lens elements were replaced by more modern and exotic Lanthanum glass, in all likelihood improving the performance. The general consensus is that there is no real difference in image quality between v1 and v2. There seems to be an internet myth that the v1 steel rim had 'special' imaging properties. That's simply not the case and if anything, the v2 was superior, due to improved coatings during its production life cycle and the fitting of Lanthanum glass after serial number 2166702.

lct Posted January 24, 2021 Share #25 Posted January 24, 2021 My pensonal consensus is that v2 flares less than v1 but last time i've used the latter was 10+ years ago so my memory may fail me . 1 Link to post Share on other sites More sharing options...
farnz Posted January 24, 2021 Share #26 Posted January 24, 2021 2 hours ago, Steven said: I’ve head that the late version of the v2 has a different coating. We can see with the NOkton SC and MC how that has an impact, so I was curious. thanks for your quick response Pete. While I agree that a different coating could indeed have a profound impact on a lens's images it's the sort of feature that I would have expected Jim Lager and the other experts mentioned above to have noted but none have in the literature I have. (Coatings on the internal elements in addition to just the external elements makes a profound difference to contrast too, as some of my older lenses such as the 73/1.9 Hektor clearly show.) I haven't come across any written support for different coatings between v1 and v2 from those in the know so, personally, I'm inclined to dismiss it as wishful thinking (or a bit of overenthusiastic 'salesmanship'? ).

Ernst Hi, Ernst, Jim Lager's 'Leica Illustrated Guide III', Morgan & Morgan 1973, shows a picture of an OLLUX (12522) hood with the script below it: "OLLUX lens hood for lenses below 2166701". I have an OLLUX hood and a v2 35 Summilux (239xxxx) and the OLLUX definitely does not fit on it, which suggests to me that the last (steel rim) was 2166700 and all 35 Summiluxs after that were v2's. Bearing in mind what you wrote above, that would mean that all v2's had the Lanthanum elements. (I had understood you to mean that the Lanthanum elements were introduced part way through production of the v2's but I apologise if I've misunderstood what you meant.) Pete.

lct Posted January 24, 2021 Share #28 Posted January 24, 2021 Excerpt of Marco Cavina (Google translation) https://tinyurl.com/yxcdnytm « As history teaches, the original Summilux-M 35mm f /1.4 was in production from 1961 to 1995 without any major modifications or upgrades to the optical core being officially heralded, although variations in the anti-reflections are evident and even small nuances in the chromatic cast or in the trend of spherical aberration in later models suggest that the glasses originally envisaged have given way to modern variants that had in the meantime replaced them, thus also requiring some adjustments to the purely geometric part, exploited to optimize certain characteristics. » 1 Link to post Share on other sites More sharing options...
pgk Posted January 24, 2021 Share #29 Posted January 24, 2021 To 'clarify' using an except out of a paper by optical engineers at Elcan (where the pre-aspheric Summilux was made): "Considering ..... the 35mm f/1.4 Summilux. LaF21 [Lanthanum Glass] replaced three elements, marked as ‘LeT29’ in the original design, at some point. We have been unable to clearly identify the latter". So there was a change in the Summilux design and whilst it makes sense that it may well have coincided with ny physical design alterations of the lens mechanics/cosmetics, there is now no way of knowing whether this is correct if Elcan themselves cannot pinpoint when it took place. There is no mention in the paper of coating changes so this must remain open to conjecture and without serious Sid-by-side and consistent analysis of various dated versions of the lens this will leave a 'mystery' surround the lens which will satisfy most of those who adhere to variations in the lens😁.

shirubadanieru Posted January 24, 2021 Share #30 Posted January 24, 2021 (edited) I’ve had the titanium version of the v2 and definitely feel it has less glow wide open than older versions. The steel rim, which I now own, definitely glows more and has a more creamy bokeh from my POV. That being said these are old lenses so I don’t know if it’s simply lens variation or actual difference between v1 and v2 rendering. I did talk with Leica collectors and sellers in Hong Kong and Thailand and everyone tells me that the type of glass used in v1 and v2 is different. I was told be the same people that the glass change happened from the infinity lock made in chrome onwards (ie the v2 infinity lock made of brass is the last batch to use v1 glass). Lastly the v1 feels way more solid and better built, with the added benefit of being able to use e41 filters Edited January 24, 2021 by shirubadanieru Link to post Share on other sites More sharing options...

It's the missing link I've been trying to find for ages. I've been unable to find any evidence of when the change occurred from v1 to v2, so thank you for providing it. I had made the assumption (wrongly, it's now clear) that by 2166702, we were already into v2 production. What you've provided makes more sense, namely, that with the new glass, came the 'new' model.

But are these advantages worth an extra 15K?! 😳🥶🥶🥶 definitely better looking & also with the coolest hood ever From a value perspective I'd definitely recommend the infinity lock v2 version. Either way, as long as you take good care of them the price shouldn't decrease, so my take is if you can afford & are able to buy it without having to get loans or do anything stupid, then buy whatever lens makes you happy 2 Link to post Share on other sites More sharing options...

Yup it’s the rarest of them all (even less than steel rim were made). I just goggled them and here’s both versions (the chrome lock which apparently has the v2 glass, and brass lock which apparently has the v1 glass). Welcome, dear visitor!
