The film is re-branded Foma 400.
There was a problem reported with their Foma 200 emulsion, in 120 format, a while back where they even stopped production of that particular film to re-do it, in an effort to fix it.
This problem looks exactly like the Foma 200 situation, which is too bad. It is, as far as I can tell, yet to be revealed what the problems were with the Foma film. But it is annoying, and detrimental to the results.
I had some of those problems myself, which ruined a couple of rolls I shot with it. The rest of the film went in the trash can.
I love how Foma films can look when there are no emulsion problems, and for the most part, they seem to give great results. But the odd chance of something like this happening is always looming, it seems.
