I just looked and prices are great for 135 haha.

It doesn't say ACROS only Neopan... I don't know the history, and I've always wondered why it had 2 names... Can anyone explain? And why would the 400 Neopan NOT be Acros?

I think Neopan 400 is classic grain (it doesn't say tabular or sigma or t-grain anywhere in the datasheet) but with fin egrain and high sensitivity. Acros is modern grain, in the same class as Delta and TMAX. I don't use the 400 but I use Acros in 120 format as my main film and I love it. The fact that it's cheap helps a bit with the love but it's not all there is to it. I hate Foma 100 even if it's the cheapest film around here - I only use it to test my film-backs for light leaks and that sort of stuff, so you can imagine the hate
