Fomapan 400 is a great and not-so-great film (when it works it really works, when it doesn't...).
I bought 100' and discovered that the entire roll has a flaw in the emulsion that records as an intermittent dark line in the top quarter of the frame...

Pretty annoying. Yes it's inexpensive, and sometimes it even feels cheap.
Can look really wonderful shot at 200 (which is how I normally rate it):

Out of necessity (lack of daylight/lack of artificial light), I've been experimenting with it at 800. The results are...ok.
