On a weekend trip to one of the few well stocked shop remained in Rome, I've come across some 35 mm film labelled Bergger BPF 200 and 400. I've bought a couple of each just for a test. The only thing I know right by now is that this film is rather expensive (25% more than a roll of Tri-X). Can you tell me something more on what I should expect from these films?

Ciao,

Marcello
