Rollei 80s is a useful film for pictorial photography. As metioned before it tends to build up contrast fast - please avoid overdevelopment. I tried it in different developers - Rodinal 1+50, Microphen and Calbe A49. The last developer, diluted 1+1, gave the best results for me.

Retro 80s has a very fine grain, much finer as 25 ASA film. It is worth getting to know. It is a bit of quirky, but one you can manage this.
