Rokkor was the brand name Chiyoda Kōgaku Seikō and subsequently Minolta used for its camera lenses. The name Rokkor is derived from Mount Rokkō (六甲), a mountain near Osaka that could be seen from Chiyoda's Mukogawa factory . it was probably also inspired by the name Nikkor used by Nippon Kōgaku from 1932. It appeared for the first time in 1940 on the 20cm f/4.5 lens of the SK-100 handheld aerial photography camera

The word Tessar is an acronym derived from the Greek word tessares meaning four. It expresses that this lens is comprised of four lens elements.

The Sonnar is a photographic lens originally designed by Dr. Ludwig Bertele in 1924[1] and patented by Zeiss Ikon. It was notable for its relatively light weight, simple design and fast aperture. The name "Sonnar" is derived from the German word "Sonne", meaning sun. It was given this name because its large aperture (f/2.0) was much greater than many other lenses available at the time

All those names have similar ends.

Is there any DB of all those cool names, please?

HA! That would be quite an undertaking! ZILLIONS of lens names exist, such as:

Apotar, Novar, Radionar, Lausar, Ensar, Solinar, Solagon, Telinear, Agnar, Skopar, Symnar, Claron, Arton, Biogon, Dagor, Artar, Raptar, Rodinar, BBAR, Takumar, Weltar, Nikkor, Westron, Sandmar, Primagon, Helioplan, Kilar, Xenar, Betavaron, Yashinon, Oreston, Dakon, Domiplan, Primotar, Cintar, Rikenon, Trioplan, Cintagon, Westar, Westagon, Ennalyt, Telemegor, Varioprox, Synchronex, Flimovara, Cinelux, Varimirax, Varob, Elmar, Elmarit, Komuranon, Omegaron, Componar, Colorstigmat, Noflexar, Culminar, Heliogon, Trioplan, Navitar, Prakticar, Sunray, Ektar, Ektanar, Biotar, Pancolor, Lithagon, Hektor, Fujinon, Varex, Amber, Trigor, Reomar, Anaston, et al.

Those are in no order (I pulled them from scratched notes and my lens DB) and are only a tiny fraction of given lens names. Yes, see Wikipedia and Camerapedia for more. But I doubt that an exhaustive list exists, especially with the etymology of the names. Hmmm, compiling such a list would be an interesting project. For someone else. Go right ahead. I had enough trouble compiling a canonical list of the name of varieties of supernatural beings. THAT was a devil of a job!

Takumar is the name that Asahi Optical gave to its lenses, notably but not exclusively those for its own SLR cameras. Named after the Japanese craftsman Takuma Kajiwara (梶原啄磨 Kajiwara Takuma?),[1] the name adorned its lenses until 1975, when Asahi switched from the M42 screw mount to the bayonet K-mount. K-mount lenses were simply named "SMC Pentax".

I'm not sure if the -ar ending means anything. I guess not. But the -gon ending comes from the Greek "gonia", which means angle. It's mostly used for wideangle lenses for that reason (Flektogon, Biogon, etc.).

That's a phonetic trick to make it sound special, connected to technology and science.

The "-gon" suffix derives from Greek γωνία [gÅnía] = "angle".

"Bio-" (as in "Biotar") derives from the word for "life" and refers to "light" (as in a "fast lens") here. The same is true for "Sonn-ar" which comes from Germen "Sonne" (= "sun").

"Flek-" mean "to bend", so a "Flektogon" is a lens that bends angles. Wink

"Plan-" (as in "Planar") refers to the plane level of the image circle.

"Tess-" derives from Greek τέσσαρες (="four").

Some lens names, such as the "Dagor", were derived from real names, here: "Doppelanastigmat Goerz" and the phonetic addition "-r" again.

So, most lens names can be traced back to some meaning. I am sure that some of the Japanese names can as well, but since I do not know any Japanese word other than "bokeh" Laughing I cannot help here.

Leitz Hektor: the lens designer Max Berek named the lens after his dog, Hektor. Supposedly the Elmax was named after Max Berek, while the Summarex was named after Mr. Berek's other dog, Rex. This is all from memory though Smile

Just read the book "A History of the Photographic Lens" by Rudolf Kingslake,
there are all the names of classical and some modern lenses. At the end of
his book, there are brief description and photo of the famous people in
the history of lens making, it is quite interesting.

Sounds like a very interesting book, thanks for the mention.


Personally I think the -ar suffix comes from "ARE you going to buy them all?!" And ARmageddon all of them! And if Spouse Finds Out, ARmagedding out of the house... Laughing

There are the 'classical' lens-type names; and there are the well-known branded names; but there are also kinky proprietary names that any dinky glass-caster could (and did) bestow upon their paltry products. Thus do we see Reomar and Optimar and Cleotar and Luxogon. As for the 'ar' suffix, I blame Zeiss. They had a success with the Tessar, and others copied.
