Field of view question.

From: Bruce
Subject: field of view question...

Hi,when comparing the specifications of binoculars on your Eagle Optics website, specifically the 8x42 binoculars, I notice there is quite a difference in the field of view between different brands. Some with 320 at 1000yds and some with 408 at 1000 yards, etc. What causes that difference and what's the benefit of either more or less field of view?



Hi Bruce, thanks for the question. The field of view of a binoculars is derived by the construction of the ocular lenses of the binocular, and ideally a wider field of view is better. A wider field of view makes it easier to find objects through the binoculars and also aids in following moving objects.

Many times, a manufacturer will not offer as wide a field of view if the optical quality isn't as good out at the very fringes of the field, so many of the binoculars with narrower fields are better at the edges than those with wider fields.

Hope this helps, thanks again.
