This is a high-speed black-and-white Panchromatic film. It is characterized by good sharpness, moderate grain, and excellent tonal reproduction. As with the Plus-X above, there is a slight difference in ASA based upon the type of lighting - without the filter, Daylight ASA is 200, Tungsten ASA is 160. Daylight ASA with the filter is 125. NOTE: When used in bright sunlight, care must be taken to avoid overexposing this film due to high speed.
