CatLABS X FILM 80 is a fine-grained slow-speed, high silver content film, specifically designed for a huge array of shooting conditions - although note that the grain visibility will likely increase with the ISO used!
Similar to Kodak's famous 'Panatomic-X', CatLABS X FILM 80 is a special treat for black and white medium-format film shooters.
Rate it at 50 ISO when shooting in under studio situations if you're looking for fine-grain, but it can be pushed up to 800 while still delivering great results.
