datasheet from filmotec germany site;
‘Exposure index: ISO 320 / 26°
The speed value refers to a developed N 75 average gradient of 0.65.’
Reference is sometimes made to it being 400 iso as well in general marketing info, (seemingly also by orwo usa) that might be a carry over from n74. Although its primarily made as a cinefilm, both it and un54 are widely used for stills too. Standard developer d96.
