Originally posted by Jonathan Mac Those look really nice - contrast is just right, great tones and almost no sign of grain. They remind me of Fuji Acros.
Much like Acros, RR 80s has very fine grain and great tonality. How they differ is with spectral reponse. Acros is billed as being ortho-panchromatic, meaning it has extended blue sensitivity and is stunted at the red end. RR 80s is somewhat opposite and has been labeled as super-panchromatic with somewhat reduced blue sensitivity and red sensitivity into the near infrared. With an IR filter mounted, RR 80s can be used for IR photography. That far red sensitivity can result in strange contrast with grass and foliage in full sun.
Example showing how reds and skin tones render:

RR 80s uses a 100μ polyester base and dries quite flat. Below is a link to white paper that was written shortly after RR 80s came to market:
