No reason for a IIIf to abstain from an upgrade made by Luigi:

hello,

I am new here, so I haven't found this thread until now. About 40 years ago, in the second year of getting a salary, I fulfilled my old dream and bought my first Leica, a M3, and somewhat later some accessories for it (Viso II, Hektor 135, Elmar 3,5/65, Summaron 3,5/35, Bellow). I used it for a long time.

 

Later, after some years of only digitally photographing, I found back to the Leica system. I then bought step by step some screw mount Leicas. Now I have a IId, IIIa, IIIc, IIIf and IIIg. The IIIc and the Summicron are in bad condition. I use the Summicron on the IIIg for the MP too, with an adapter. I purchased the the IIIa just some days ago, because I have got with the IId a Geiss Synchron Contact suitable only for a IIIa. So, obviously, I was obliged to buy the camera for the Synchron Contact. Now I am planning to use the IIIa with the Geiss and a CHICO flashgun. I'll try to get some old flashbulbs for that via ebay.

Lovely collection of cameras Bernhard! And the sought after LTM Summicron ASPH!

I found the LTM Summicron ASPH at the internet presentation of NEWoldcamera, Milan (http://www.newoldcamera.com). The description was similar to the following one:"Interessante 35mm f2 Summicron ASPH. in versione Silver prodotto per il mercato Giapponese. Le differenze tra versione M e questo modello speciale sono ; la minima distanza di messa a fuoco , il peso e scritta su frontale ma sostanzialmente è uguale a 35/2 Summicron-M ASPH. Silver . Può essere utilizzato su corpi M con anello V-M ."[/font]

The internet presentation of NEWoldcamera is only in Italian, but it is possible to write and get an answer in English. The purchase was simple: I transfered the money in advance, in confidence of the reliability of the firm, and I was not disappointed. Some days later I received the lens.

 

Best regards

Bernhard

Bernhard: Has the Summicron on that poor condition Leica got bad cleaning marks?

I just wondered what had happened to the camera for the chrome to start coming off the base. Is the damage to the camera body only cosmetic?

 

I don't think that the Summicron has cleaning marks. I'm not sure but I think it is a fungus. The front lens has a regular pattern with a lot of small round isles and lines. The pictures made with this lens are of no use. They are, especially in the center, very hazy.

I have read too, that the chromium shortly after the war was of less quality. The damage of the camera is only cosmetic; it works fine.

Best Regards

Bernhard

That looks like etched glass. The classic for of fungus is radiating fan-like growths.

Although it looks like there are marks on the lens elements they seem to not be present around the edges of the image. That sample image seems sharper at the edges. This could be a balsam fault perhaps?

 

As for the defective chrome: The fable I heard was not that there was a shortage of chrome, rather a shortage of nickel. To plate chrome the brass has nickel deposited first, which is plated with chrome to ensure a durable finish.

 

 

Is it a massively expensive business to get a 50mm Zeiss Sonnar changed from Contax bayonet to 39mm Leica screw?

Could be cleaning marks. I have a 4/90 that looks like it was cleaned with steelwool. Makes you wonder what on earth the previous owner was thinking...

 

I have seen examples of the collapsible Cron. where the soft coating has gone pear shaped and it end up looking cracked, dried out and flaky.

 

Apparently Leica used to dip coat their early lenses. Zeiss lenses were coated by a process of vaporization, which yields a much harder and durable coating. This is the process used today.

Hello Thrid, thanks for your steelwooltheory. If I imagine cleaning a lens with steelwool I would expect sharp lines and circles on the glass. But on my lens are a lot of little points. So I think marks by etching as Neil suggested are more likely. Whatever the cause for the marks may be, I wonder whether the lens can be mended at a reasonable price. Did you check mending for your 4/90? Have you found an answer?

Regards Bernhard

Hey bschererwi

 

The 4/90 is beyond salvaging, but it makes for a great soft focus portrait lens. The scratches impart a beautiful glow.

 

As for as your Summicron there are a few options.

 

First off I would shoot an email to Don Goldberg at DAGcamera or Sherry Krauter of Golden Touch. Email them a photo and see what they think.

 

I would also talk to Henry Scherer at

 

The Zeiss Ikon Contax Camera Home

 

He's a Zeiss man, but extremely knowledgeable about these sort of things and may be able to help you.

 

Also talk to John van Stelton, who can apparently polish elements and recoat them.

Hello Thrid, thank you for your recommendations. They are helpful. In addition, I found a thread about a similar Summicron frontlens (http://www.l-camera-forum.com/leica-forum/leica-sammler-historica/43421-summicron-1-2-0-50mm.html). Regards Bernhard

I'm new here, but, I'd like to be included in the screwmount census! A III with several accoutrements and a II with a tweeked J3 as my daily carry camera.

My little collection:

 

1938 Standard, 1937 IIIa, 1932 Elmar 5cm (modified to fit NOOKY permanently and ruined imo), 1937 Elmar 5 cm and 9cm and 1946 Summitar. Plus the usual assortment of hoods, filters, view-finders, ERC's, Directions, Catalogues etc.

 

And some more modern stuff of no interest in this section: except for the Voigtländer 35mm lens. And a similar collection based around the, much later, USSR Fed 1 for comparison.

 

Regards, David
