Fixed "proto-" reference
Jun 3, 2014 at 17:16 comment added tchrist Although -ar for argentum might be pushed, I feel that the infix -t has not been accounted for. Y a-t-il, peut-être, quelque autre possibilité qui explique ce phénomène curieux? Ok, viewed synchronically that’s not true epenthesis, thanks to the old Latin -t in 3sg pr ind act verbs. Certainly Japanese requires epenthetic insertions of foreign words, as of course in certain positions does Espanish. But the tradition seems to have begun in Germany, so there must be something else to it.
Jun 2, 2014 at 22:24 comment added David Richerby "Protargol" just happens to contain the sequence of letters t-a-r. As shown by your etymology, the t is part of prot[ein] and the a-r is part of arg[entum]. And, like @phenry, I see no reason why people would name their lenses with a suffix derived from a chemical used in film. It's like suggesting that a name component of a car engine is derived from a part of the tyre.

Incorporated comments on Pro- part of the name
Jun 2, 2014 at 17:12 comment added P. O. According to Zeiss, Protar was named so because it was the first of a serie. I think OP maybe right, due to the success of Zeiss with their -ar series, other copied the pattern. See explanations for other lenses as well: sony-mea.com/microsite/dslr/09/carlZeissLens/…
Jun 2, 2014 at 17:12 comment added phenry Possibly, but then I would expect to see the suffix applied to film stocks more often than lenses. The only film I can think of that fits the pattern is Kodak Ektar, which was introduced more than 50 years after the first Ektar lenses in a pretty clear example of brand extension.
