There's some confusion over which versions were five-element, which I try to explain below. Turns out that's the easy part . . . working out which versions have the concave-5 diaphragm is the real headache.
-----------
Version 1 [10146]: Produced 1975-1981. Five-element, concave-5 aperture. Single-coated.
Version 2 [14849]: Produced 1981-1990. Optically identical to [10146] but with aperture illumination and lever. Single-coated.
Version 3 [Catalogue # unknown]: M25 mount version of [14849]
Version 4a [16828] V1: Produced 1990-1995. New six-element design with concave-5 aperture in BLV-L. Similar appearance to [14849] with crucial minor differences. Lenses produced in 1994 have the same curved-5 diaphragm as [16828] V2, but no green band. Multicoated.
Version 4b [16828] V2: Produced 1995-2008 and beyond. Same six-element design as [16828] V1 but all models have curved-5 diaphragm in BLV-L. Green identifying band. Multicoated.
Version 5 [18827]: M25 mount version of [16828].
Version 6 [14796]: V-mount version of [16828] with Makro Iris body.
Version 7 HM [Catalogue # unknown]: Produced c.1993 in unknown quantities. Likely industrial or high-magnification application. Seems apochromatic.
Version 8 V2 [1097301]: Revised optical design produced from 2020-2021 and marketed as an industrial lens in V38 mount only, but equally suited to enlarger and taking application. Max aperture now f32. All metal body.
Version 9 Pyrite [1097301]: Produced 2021 to date. Rebranded version of V2.

If anyone has the catalogue number for the M25 version of [14849] I'd appreciate it.
Also, I'm keen to track down examples of the Schneider Componon-S 50mm f2.8 with serial numbers between 14,372,274 and 14,440,675.
And if you have an example from 1994, I'd love to see a picture . . .

Great investigation - that's way more thorough than anything I've ever seen on that topic! I didn't know there were so many of them.

Even though it's from 1979 in the current form, the Nikon "Micro-Nikkor 55 mm f/2.8" comes to mind immediately...

It's really strange how they managed to create somewhat known names for these lenses and now they lump them all together under "Pyrite", just to fit them into their new naming scheme... The Macro-Symmar and even the Macro-Varon are also included under that umbrella apparently. But hopefully at least you won't be buying a Componon-S 80 mm for three times the price labeled Apo-Digitar. now...

Yeh, no. Buy a Componon-S [16828] for one quarter of the price of an Apo-Rodagon N instead . . .

I can't find any serial number on my S-COMPONON 50/2,8, but it is the best normal lens I have (I have many), no distortions of any kind, remarkable sharpness and resolution. It is sitting on Sony, attached by helicoid. |

The serial number is probably hidden by the helicoid: many versions have it printed on the rear element housing. Which version of the ones listed below is yours?

Looks like it is old Componon-S version, black with split white circle. Any way it is perfect lens, sharp corner to corner, image is perfect geometrically, zero CA. I'm taking a lot of museums photos, it is important quality this, and another enlarger lenses have.
My every day shutter bug contains this one on helicoid plus Componon-S 100/5,6 ; Graphic Ektar 127/4,5 and Apo-Gerogon 210/9 on bellow. However for the wide angle I have a tiny, Sony dedicated, Sigma 19/2,8 AF, which is crop formate but sharp enough to be cut in many way without a big losses for the image.
This universal set is acceptable for my old shoulders  |
