... and a Skopar a Skopar, and so on, about the VC lenses ?

Is there a quality difference ? What's common between lenses of the same series ? Maybe it's obvious, but I'm a beginner at this (and new to the forum) ..

Should I care about the difference (if any) ?

Thanks,
Stefan.
 
I believe it used to mean something (original Voigtlanders in the 30's-60's) but I think nowadays it's simply names with little meaning anymore...

Its "nokton-ness"?

Explanation of joke:

Metaphysics is regarded as “first Philosophy” insofar as it is concerned with issues and questions that are, to quite an extent, the most fundamental of issues and questions, as is the case when we wish to discover “being qua being”, or being understood as being...

...In the Aristotelian paradigm, he employs a rather cause-oriented approach of analysis, where we discover what the object is (causa formalis), who made the object (causa efficiens), of what the object is made (causa materialis), and what its teleological purpose (causa finalis) is. For instance, we have a chair (causa formalis), by the carpenter (causa efficiens), made of wood and nails (causa materialis), and meant to be seated on (causa finalis). Even if the chair may be made of ivory instead of wood, i.e., a special quality, we still recognize it as a chair, regardless. In what on the surface may appear to be an offshoot of the Platonic notion of the Eidos, then this so-called copy of the idea of a chair may have variations indeed, but because of its “chairness”, as it were, we can still safely call it a chair.

Hence, if one subscribes to the Platonic (as opposed to the Aristotelian) metaphysical paradigm, what makes a Nokton a Nokton is indeed its "Nokton-ness".

Hey - don't Nok it.

Nokton, Nokton...

These were indeed names given to Voigtlander lenses in days gone by. The Nokton was, for example a fast lens designed for the Voigtlander Prominent rangefinder camera (and others possibly - I have not checked.) The Skopar / Color-Skopar was a slower lens design approximating the Tessar and the Elmar designs. A version of this was also made for the Prominent but in this case I know it was also used for various other cameras too. In short the names derive in each case, from a particular lens design, much as Leica does with its naming conventions. Its a quaint old German tradition to name lenses and this seems to have caught on again recently. And I suppose there is some cachet to having a well respected name of long lineage.
 
I think it's the aperture like the names Leica uses.

Nockton = 1.4ish
Ultron = 2.0ish

I think the Skopars and Heliars refer to design.

Noctilux = 1.0
Summilux = 1.4
Summicron = 2.0
Summarit = f2.5

After that it gets confusing.
Elmar/Elmarit/Summaron = 2.8 and 3.5 and 4.0
