This film is marginally better than Agfa's APX100 but not nearly as fine and sharp as T-Max. No matter what Ilford says ! However it is on a thinner film base, which is important for some roll film cameras, and does offer better processing latitude. I personally rate this film at an EI of 64. Of course it depends on the subject contrast range, developer choice and processing standards that will be used .
