Just to open an old wound, wasn't the official reason from Fujifilm for Neopan 400's discontinuance in 120 that there was an environmentally unfriendly component in the backing paper? Well, being no chemist myself, I have just noticed (and I don't know why it took me so long) that on appearance the backing papers for Neopan 400 and Acros 100 are exactly the same. There is nothing printed on either of them to identify which film it is. The only identification of film type is on the packaging and on the sticky tab at the end of the film. Have Fujifilm conned us?
