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

[Ed Schwartzreic]

Hi Kevin, thank you for the kind thoughts. I sincerely doubt I will be disappointed! And I don't really mind waiting.

It is my concern, as expressed by some others here also, that you, Mr. Zhou, and everyone involved take whatever extra time may be needed to produce these lenses, given the potentially difficult circumstances which we read about.

Hi Kevin

I've sent you an email. Can you send me an application form for the next available batch please?

Thanks

James

Now all you need is an 8-element cross-section tattoo that matches the diagram on the lens cap!

Hmmm ... will have to think about that.

Several years ago I traded away my 35mm Summicron V1 (M2 model) and I kept the goggled Summicron which I still own. The replica will replace the lens that I traded away.

Here in northern Vermont, we just had a couple of days of storm, and today the sun came out. There is little up here usually to take pictures of this time of year, but I took out the 8-element prototype and shot a series of images of snow on the trees. M10, ISO 200, either f/5.6 or f/8. Only in bit of exposure brightening in PS, one image is cropped slightly.

See what you think.

Lens has a nice rendering.

Do it! I believe it was Archimedes who said that "Give me enough alcohol & peer pressure, & I can move the world!"

I can see moire patterns at infinity on the edge of the tiny branches of trees, suggesting that this lens is super sharp to the point of going over the limits of the sensor.

 

[Ed Schwartzreic]

You raise an interesting question about moiré patterns. I can see them in places too, when I magnify to 200% or 300% on the original image. I can't say whether uploading the images to Flickr and then to RFF may add artifacts in any way.

I have not really thought about such with the sensor in the M10, with its minimal anti-aliasing filtration, but perhaps someone here can address how much of this might be present with an "ideal" lens, given the other parameters of digital photography.

At the very least, for the 8-element replica, comparison to the original lens ought to be made to look at this side-by-side IMO. I don't think the weather tomorrow will be very cooperative for this, but if it is, I will make such a comparison.

I expect to find images to be very similar in quality for the original and the replica. I give a small edge to the replica.

 

[Ed Schwartzreic]

FWIW I made images of more snow-covered branches at infinity with both the original 8-element and my prototype replica at f/8. I also did the same with my reference lens (for resolution) - the 50/2 Apo-Aspheric. I could see little difference with any moiré effect amongst the lenses (there was definitely some of it with all lenses - versus merely visual evidence of the pixel array, difficult to be sure which).

The prototype replica was slightly sharper, I think, but not very much than the original 8-element. Contrast was of course somewhat higher with the 50 AA.

Thanks for this additional test, Ed
I expected such findings.

[LHSA Viewfinder 52-3] A NEW OLD 8-ELEMENT 35/2 from China by ED SCHWARTZREICH

With the help of Bill Rosaour, LHSA President Emeritus and Viewfinder Journal Editor, I get a chance to work with Mr. Ed Schwartzreich from LHSA for his review of the Leica 35mm f2 Version 1 Replica lens publish on Viewfinder magazine. This is our honor that our Leica Replica project gets attention from Leica Historical Society of America and able to reach a broader audience. With all the support from the Leica community, we are very encouraged and confident about our future project.

I appreciate that I could get permission from Mr. Ed Schwartzreich to share his article on the RF forum. Please enjoy.

Cheers,
Kevin

Amazing! Congrats for hitting it big!
Can't wait for mine!

 

[CharlesDAMorgan]

Excellent write up - that is very satisfactory!

 

[D&A]

Simply a wonderful writeup and much thanks is owed to Ed, Kevin, Mr. Zhou and the design and production team. The accompanied test images, MTF curves and explanations, extends the phenomenal interest in this and future lenses. Like many others, I am eagerly awaiting the arrival of the lens and most of all not only using it for a variety of uses, but also looking forward to images made by others. That alone should be a very interesting thread.

Thank you for your patient. I wish things could moving on faster. But there are also many things outside our control. We will do our best to fulfill the orders here when people are back to work.

Kevin

Thanks for the update Kevin. Like everyone else, I don't mind the wait.

Regards

[taemo]

congrats on the recognition! looking forward reading the article later this afternoon.

I just sold my CV 35mm f2 Ultron last night in anticipation of this lens. For the time being I will be shooting with the collapsible 50mm Summicron as I've been neglecting this focal length lately.

Thank you Ed for the write-up and Kevin for the sharing with us here.

Wow! - I can see the cell phone tower on the ridge of the mountain in the background. And the branches of the trees are so well defined. I also agree there is some moire pattern in the trees as others have mentioned. However, I think the rendition of the snow in the highlights is outstanding. Is this the lens or the M10?
