Field of View is the term for the width (and height) of the image you see through your binoculars. Field of view plays such an important role in the viewing experience that many birdwatchers rank it among the most important specifications for binoculars.

Field of view is very important when you’re finding birds in flight, looking for a bird in dense foliage, or following a bird as it moves. A wider field also leaves more room for error when you put your binoculars up to your eyes, allowing the bird to stay within your binocular image even if it’s not right in the center. A bigger field of view is particularly helpful for people new to birding, making it easier to find birds when putting binoculars up to their eyes.

The two most important specifications for binoculars are the magnification and objective lens size (that’s the “8” and the “42” in “8×42,” respectively). But it’s also worth paying attention to Field of View. Whereas magnification and objective lens determine how big and bright your image will be, field of view (as well as Close Focus) determine how much of the world you’re able to see.
