[New test photos released] Leica Summicron 35/2 Eight Element copy made in China

[raid]

I found [one time only] a Steve Huff link in which he compared 50/1.2 to 50/1 to 50/0.95 to Hexanon 50/1.2 and Hexanon 60/1.2.
Now, I get "access denied" when I Google for it.

(The closest focus of the LTM version will be 1 meter, as the original one.)

This is a mistake, make the min. focus distance same as M mount.

This is a mistake, make the min. focus distance same as M mount.

I'd prefer that, too. My Canon 7 goes down to 0.7m. But then I'm interested because it promises to be a great lens, not because it's a replica of something... I'd also prefer multi-coated... but also I get the idea of a more authentic replica, it's just not a priority for me.

I was able to open what may have been the Steve Huff's piece in question. It was here:

In the book "Vive la France", by Henri Cartier-Bresson (1970), many examples of pictures with the Noctilux 50mm f/1.2 are to be seen. The title in English is: "Cartier-Bresson's France".

Great as these pictures are - because they are made by a great photographer - they killed off my desire to own a Noctilux 50mm f/1.2. There are lots of distortion, unwanted unsharpness and low contrast to be seen.

The Voigtländer 50mm f/1.1 is a much better lens.

Update on the Leitz 50mm f1.2 AA Replica project

Update on the Leitz 50mm f1.2 AA Replica project

UPDATE:


Here is an update on the Leitz 50mm f1.2 AA Replica project.

The maker successfully replicates the special Leitz glass No. 900.403.

Here is the first successful sample of No. 900.403 glass.

Making the sample of the special No. 900.403 glass for the next replica project. by Kevin-Xu, on Flickr

Here is a video clip showing the making of the special replica No. 900.403 glass. Above 1300°C molten glass was pouring from the crucible into a pallet and allowed to cool naturally. Original No. 900.403 glass consists of 12 different chemical ingredients include the high amount of Lanthanum oxide and tantalum oxide. They are very hard to melt. And these materials are very expensive, by the way.

Note: This is for the example analysis only. To test whether the glass meets the standard of the original No.900.403 glass.

Seen the photos and they were not impressive. The NOCT Nikkor appeared to be a better performer. The Noctilux 1.2’s appeal lies in the unobtainium chic. The new CV 50/1.2 rocks and superior to the old N’lux.

Here is my evaluation of 50mm lenses for the Leica, entitled the "Bokeh Kings" that I wrote for the LHSA Viewfinder. I included the 50/1.2 in the results.

Erik.

Regarding the performance of this lens, the maker said that the individual differences of the original Noctilux-M 50mm f1.2 are relatively significant. He believes that the making of each lens element could be controlled more accurately by modern technology, and the best element will be selected for the best matching lens group. Thus, it could finally make the optical performance of Noctilux- M 50mm f1.2 reaches its best effect.

Hi Erik;

I read somewhere that you got a prototype of 35/2 replica to test. Is that correct? If that was the case, how is your evaluation of the lens.
Thanks,

Thank you, Ed. I may buy the 50/1,2 replica if the price is manageable to me just out of curiosity and because I like using 50mm lenses.

Here is an update from the maker. The manufacturing of the retail version 8-element Replica is now in progress.


The technicians are assembling the lens core for the first batch of the retail lens.

These two pictures are the replica lens hoods they produced. It is currently in a semi-finished state. The brass material is first oxidized and blackened, and then painted with black paint. After regular use, the lens hood will show brass over time.

Hello


I'm following this thread from the start and I'm still amazed by the commitment you have . Making a replica seems in some aspects more difficult than making something that just "look like" . For instance , you seemed to struggle with flare . It reminds me of a discussion with the french Contax importer like 20 years ago explaining to me that Zeiss used up to 14 different anti-reflection black paints to put on the side of lenses , depending on ... a lot of parameters . You'll be outing a screw mount version and I was thinking , why not making this lens like the first original version with removable mount . Or we could just buy the SM version and a Yeenon mount like this one : https://www.ebay.com/itm/Yeenon-Lei...835100?hash=item3d86c1875c:g:C4gAAOSwHnFVxW1b
( no link with the seller , never seen the product )
In a previous reply , I was suggesting a black matte finish , and you explained to me it was not possible . Any update or no hope ?
Regarding the coating , my wish would be not particularly SC or MC but the hardest one . Do you have an advice on the toughness of the different coatings ?
I don't remember if it's been asked : 6bit coding option or no hope ?
And regarding your next project , the Noctilux 1.2 , I mean , what a challenge ! Do you use the same frightening method by dismounting old ones or a more theorical approach ? Are you afraid of the coupling that seemed problematic back in the day ? I'm personnaly interested in this lens ( tried it once on TMZ long time ago ) because of the unique concept approach : a ( apparently ) simpler optical formula to achieve max clarity no matter the drawbacks ( astigmatism , fine detail sharpness and distortion ) . Will the fidelity to the original go to the unusual 48mm filter thread ?

Please excuse me for my approximate english and for asking so much questions at a time , but eventually it's all your fault 🙂 .

Yes, a great test! I really enjoyed this one. I always regretted it however that there was never a part II, AFAIK.

Personally I am now fascinated by the black version of the Summilux f/1.4 v1, only 400 made (plus some custom made ones) wich is the best high speed 50mm I have ever seen. This lens is different (tweaked?) from the normal chrome version of the Summilux 50mm f/1.4 v1. Different coatings too.

Leica MP, Summilux 50mm f/1.4 v1 black (serial no. 1703XXXX), 400-2TMY printed on Adox MCC 110. Full aperture.
