Hi Ulrich, I bought one roll  this week. To my experiment it is very good
for  blue light, perhaps as good as PJM (or even betther) but *much* less
grainy. Pretty good reciprocity failure (but to my sensatoin not as good as
E200), neutral background and very well balanced. Not as good as E200 to
reveal red light but the rediction of this color is better to my taste than
E200. The only problem to me is that it is slow, I mean that definately it
is not a 400 asa. A magazine here in Italy rated it 320 asa dor daylight
work. We are going to take some pics this week-end also with this film on
various objects. I  have re-scanned my M31 image taken on this film, if you
want to see it I'll send it by mail since I am not ready yet to put it on
line on my web page.
Ciao
Marco
