Filed of view for Binoculars:
Your binoculars' field of view is the width of the area you can see. It’s usually described in two ways: angular field of view and linear field of view.
Angular field of view is the true angle seen through the optics and is usually measured in degrees. The linear field of view is the width of the area seen and is given in feet observed at 1000 yds. A larger number for either angular or linear field of view means you see a larger area. Field of view is related to magnification. In general, a greater magnification yields a smaller field of view.
