is THIS fungus or something else?

And tbe coating was invented in 1935. So maybe these lenses were already coated

"The Model 3A Folding Ansco was produced from 1914 to 1932."
According to you maybe the lens was coated already from 1935, right?
You don't believe in Moon landings, do you?

Can you show me a single photo of a coated photographic lens from 1935, please?

Pfsor, Alexander Smakula of Zeiss patented lens coating in 1935. See https://books.google.com/books?id=AO...oating&f=false

That said, coated lenses for civilian use came in after WW II.

With respect, you should learn to recognize invincible ignorance and ignore it.

Coated lenses were already used during wwII. Not only after.
I wasn’t refering to the ansco camera. I was speaking in general.
It was invented in 1935, the Germans started using it already at tbe beginning of ww2..
So what’s the problem with my question?
I only said that i have never ever seen a non coated lens with fungus.

Lens coating was recognised as such already in 1886... and led to lens coating later. In between fungus changed its appetite but not so much that it would not create problems during WWII. Ignorance is bliss. So are drogues - for a moment. It devastates you after. Never mind.

Google is your friend.

If you know the difference between fungus and separation of the balsem you wouldn’t post these links.
Both lenses shown in these links have a separation problem and that’s a totally different thing.
Fungus has a much finer pattern.

I have seen fungus growing on an old pharmaceutical bottle from late 19th century. It had the same appearance. It was not coated. It was not balsamed either.
But then, different people see different things. Only physics is everlasting. Have you seen water from Mars?

You win. Good luck!
Next time check what was being used in the pharmaceitical bottle...��

Hey Brother Dan! Agreed & Just added one more to the Ignore list.

Not convinced by your examples!
The long restoration says "the fungus was cleaned off with alcohol" - which is my experience too!

Time to restore your reading comprehension skills, Steven if you want to have an honest intellectual debate. The fungus was cleaned in this way - "Fortunately, much of this material was removed by a determined cleaning with Windex on a Q-tip."
Windex is not just alcohol. 5% of it is ammonia, not to speak about the other potent stuff in it. A determined cleaning with Windex for something "not attached to the lens surface"? Where was the fungus, right over the surface in elevation?
Perhaps Rand Collins MD - Author of Through A Vintage Lens - knows how to recognize fungus better than you can from a picture?
