It can go to 3200 and do it pretty well. Compared to a limited use of Delta 3200, TN 3200 produces better grain, but the tone range in contrasty light is a bit weak. (But, you'd expect that any way). Overall, this is a nice film. It has a host of issue because of its chromogenic status. There is plenty on this in the photo.net Q&A; search there.(posted 8618 days ago)I would test a few rolls and see how you like the grain, contrast, and resolution.
