Isco often associated with Schneider as part of it. Actually it become part of Schneider after (if not mistaken) 1990. So this lens doesn't has relation with Schneider Kreuznach. Well this lens have a look like Schneider lens, bt perform different than SK Xenon 50/1,9, specially it's bokeh.
I like the look of this lens. Keliatan gagah, sayang gaada tutupnya
