Rollei RPX 25 B/W negative film 135-36 (35mm)

Manufacturer's description:

Rollei RPX 25 is a panchromatic low-sensitivity black and white film with a nominal speed of ISO 25/15°. In addition to its extraordinary fine grain, the Rollei RPX 25 has a very good resolution and high edge sharpness. The Rollei RPX 25 is characterized by a high sensitivity reserve of one f-stop, depending on the development. The thin-film silver-rich emulsion is cast on a crystal-clear base and has an excellent performance ratio between image quality (sharpness/fine grain) and sensitivity utilization.
