But I can comment on resolution, sharpness and grain of the new films. And concerning sharpness and resolution these new Fuji films are better. For example we've got 120 Lp/mm resolution with Fuji's new ISO 200/24° emulsion (without the additional layer). In the same test the Kodak Ektar 100 resolves 105 lp/mm. And this emulsion is very sharp, much sharper than Kodak Ektar 100. The Fuji film has significantly coarser grain, but also significantly better sharpness and resolution than Ektar 100.
This is great to hear. By the way, how can I tell which films are the older ones and which are the newer ones by the box or label?
