With the conventional method used previously, the apparent field of view was calculated by 

multiplying the real field of view by the binocular magnification. After revision, Nikon’s 

figures are now based on the ISO 14132-1:2002 standard, and obtained by the following 

formula:

Referring to the ISO 14132-2:2002 standard that was established at the same time as the 

abovementioned ISO 14132-1:2002, binoculars that provide an apparent field of view over 60˚ 

are considered wide-viewfield binoculars.
