2025年2月9日 · The Field of View (FOV) is a crucial aspect of binoculars and monoculars that directly influences how much of the scene you can observe at any given time. Understanding the trade-off between magnification, FOV, and other factors like lens size and design is essential when choosing the right optical device for your needs.

Field of view at 1,000 meters is the width of the visible area at a distance of 1,000 meters, which can be seen without moving the binoculars. For example, with 8x42 7.0° binoculars: Field of view at 1,000m = 2 x 1000m tan (7.0÷2) = 122m
