Added 2 lenses to the Isco collection. Already got one Tele-Westanar 135 3.5 'zebra/red/window'. Not sure but looks like the Westagon (on Edixa in pic) matches the Westrocolor 50 1.9 and is of same outer design as the 135s. Is the Westagon same as Westrocolor, just different names, or is the optics/blades any different? Do they optically match the Schneider Xenon? Is there any other lens, apart from the 35mm 2.8 that share the outer design?

Excellent question! I don't know. Isco naming convention seem a total conundrum to me. Nice lenses though, both isco in general and the ones in your photo. The look of that particular version is one of my favorite lens as to cosmetics design. Just elegant.

Yeah, that particular series is real lookers and all metal high quality. Is there any Isco that really stands out optically and one that is good to stay far away from? Alu ones looks nice too but quite slow. If someone got any interest in the camera bits and bags send a pm, not collecting Edixa stuff.

The Westrocolor 50 1.9 is a very nice lens and performs very well.

Is the Westacolor 6/5 or 6/4 design? I find claims of both on google. |

 I wanted to ask the same. The bokeh for one looks very similar (i.e. absolutely lovely!).
They certainly are related in some way, just as Schneider and Isco are. But how much? Are they the same?

I love those zebras. Optically, they are average IMO. You still miss the 35mm in your collection

"Feelings" can be deceptive . I just have compared an ISCO Westagon 1.9/50 with a recently acquired ISCO Westrocolor 1.9/50, and their performance is quite different (landscape images, 24 MP FF sensor). The Westrocolor is clearly better, and its performance and rendering remind me of the classical SLR Nikkor 2/50mm.
Looking for some more informaton I found that the Westagon (around 1952) in fact is a different design than the Westrocolor (around 1958):
https://photobutmore.de/exakta/isco/
Westrocolor (for Exacta) was also marketed as Westromat (for Edixa-mat).

Here are some possible designs from different sources:

Thanks a lot! From your information it's obvious that the Westagon 1.9/50 and the Westrocolor 1.9/50 are different designs indeed.
Very helpful!

Agreed, very interesting information. Now I don't feel so bad about owning both versions
As to whether they are the the same as the Schneider Kreuznach Xenon 50/1.9 it's difficult to tell with certainty.
Diagrams are available at:
https://photobutmore.de/exakta/schneider/
https://photobutmore.de/exakta/isco/
The page for Schneider Kreuznach shows two different diagrams for the Xenon F/1.9, they do look similar to that of the Isco lenses as well. One thing (some of) the Exakta versions of the F/1.9 lens have that the Isco version does not is a super cool PAD 18 blade aperture, somewhat of a record for an automatic aperture, partly made possible by the extra mechanical force able to be bought to bear by the use of the finger to activate the aperture. Even then, they often need servicing to restore correct function. |
