Hi, Mike,
Looks like it works well as a soft portrait lens. I'm all for using
these interesting German lenses, no matter how they were all supposed to
be derivatives of triplet or Tessar or Planar or Sonnar designs.
Checking back the archives I saw the discussion about JSCO vs. ISCO.
I have seen Joseph Schneider Co. mentioned as well, saying ISCO has the
same roots as Schneider Kreuznach. A Google search on "Joseph Schneider
isco" yields this page:

Which all but confirmed it. More interestingly, the beer bottles
>From Springfield, IL used to have Schneider optics! Perhaps the beer
bottles in Illinois were the lesser ISCO, while the wine bottles in
Rhineland were the more expensive Schneider Kreuznach:-)
Cheers,
Yefei
