The f-number isn't the one that tells you how much the lens will see. This number is more like the quality of the lens -- its light gathering capability.
If you paid for f/1.2 and you got f/1.4, you got a lens of lower capability than advertised.
The focal length is in "mm" -- I think you said it was 2.5mm. This will tell you how much area it can see. 2.5mm would make it more like a "fish eye" lens. 8mm is the one that is neither zoom or fish-eye. 12mm is 1.5x magnification and 16mm is 2x magnification.
