Focal length designation
 
Hi All,
Here is a question for those in the know:
I am used to seeing a single number for focal length in the EXIF data such as:
Focal Length: 39.1 mm.
But I am confused by
Focal Length: 468/100 mm.
Am I to take it as 4.68 mm? Any thoughts?
Thnx,
MT

Can't possibly be true! Extreme fisheyes are 8mm. Frankly I don't know what it means.
