I think that the pancolars 1,8/50 and 1,8/80 were made with schott glasses.

And read that the pentacons - meyer - were made with poland (not schott) glasses.

Anybody knows about that?

I don't know.


But I like to use this thread to ask something that I has confused me for a while now:

Aren't "glasses" the things you wear on your nose and look through?
"Glass" is the material you make lenses from, right?
But how do you say the plural of "glass", like in different types pf "glass".
Would that be "glass" (as in "fish" pl.) or "glasses" (but how do you differentiate that from "goggles").

I guess the easiest way to make it clear is to refer to different "(optical) glass types" or "sorts of (optical) glass"

"Glasses" is OK. You differentiate by the context - although there might be some ambiguity as this thread illustrates.

Seems that no.

Rino - sorry, I don't know the answer to your original question. I do know the answer to this one, though.

Yes. Also the plural of things you drink from: "after the party, the kitchen was full of dirty glasses". Although, the thing you wear is more fully a "pair of glasses", thus its a singular object that looks like a plural (same for a pair of ninoculars, a pair of trousers (that's pants, in US English).

Depends. As an adjective, it would be singular: "the lens is made from eight glass elements" (elements is plural but they are all glass). If the intention is to show the multiplicity of glass types (note in that phrase, types was plural but glass was singular) one could use a plural: "the doublet was made from crown and flint glasses" but once could also say "both crown and flint glass are used to make the doublet".

OK, so that's what Schott glass is made from.

As opposed to a shot glass

err... so, Zeiss used SCHOTT glass, while Asahi used HOT glass. Does the lack of S, C and one T mean any difference?

Free academy?

It's good.

When the course of English finishes, probably we can talk about the thread

I think they are used different material after WWII I read somewhere this they used different glass as raw material this source said this is reason why all Meyer soft compare with sharp CZJ. I don't know is it truth or not. In my experience pre-war Meyer and pre-war CZJ are identical quality even in sharpness and I saw huge difference on post-war lenses. Early post war lenses are really good from Meyer too, trouble came out later. Perhaps no related with raw material might be Klaus or somebody else know the answer.

So Rino, whats this Polish glass you were talking about? Google draws a blank for me (I did look, before posting jokes).

I don't know, for this reason I asked it to the guys forum, that they are always so amiable in sharing knowledge.

Yes, mi english isn't good, as you can note, but I'm sure that you will do the effort to understand Laughing Laughing

The region around Görlitz was one of the main centers of the German glass industry, and Meyer sourced their glass locally or regionally. After WWII, the eastern part of the city, Zgorzelec, became part of Poland, and with it, several of the local glass makers. It is at least possible that the partner of choice was situated in Zgorzelec, or that Soviet planning for the region assigned the role of the optical glass maker to a combinate on the Polish side. I'll see whether I can research this later this year.
