Rollei RPX 25 sheet film 4x5" 25 sheets Rollei RPX 25 is a low-speed panchromatic black and white film with a nominal sensitivity of ISO 25/15°. Aside from the extraordinarily fine grain, the Rollei RPX 25 has great resolving power and high acutance. Rollei RPX 25 is characterized by a high sensitivity reserve of one f-stops, depending upon development. The thin, silver-rich emulsion is coated onto a crystal-clear base and offers an excellent balance between image quality (sharpness/fine grain) and speed yield.
