Thanks Herman, I'll look into that!
Chris,
I just took a quick look at the manual. This device allows you to store the data from yr F5 on a small CF card. The F5 data can than be imported as a text file into Excell to be manipulated. In fact, with the F5 there are 4 recording modes with increasing complexity <A, B, C, D> with up to 15 exposure type data.
Depending on complexity of the data, the F5 allows you to record/store up to 78 rolls <36 exp.> in basic . It seems that if you have a MF-28, you can increase the number of data you record.
PS: Nikon Europe has a pdf of the manual , it's size is 3 MB. The manual like any other Nikon manual takes some getting used to...
I vaguely remember that a while back there was a thread on this topic, either here or at Nikonians or Nikon Gear.
Have fun!
