Many of us use our film at nominal speed, which means that a roll of 100 ASA is going to be shot as that, 100 ASA. Not fancy speeds, so not 80, not 125, just plain 100. We know how to set these speeds, and is a pretty straightforward thing to do. However, when loading your camera with say, Rollei 80 or Ilford's FP125 and wish to shoot at film's nominal speed, what then? Well, Minox has the means to register intermediate speeds, so have a look lower on this page. It could be that one day you'll need to know this simple procedure.
