Swift 8.5x44mm BWCF Audubon Waterproof ED Binoculars 820ED Product Info

Swift 8.5x44mm BWCF Audubon Waterproof ED Binoculars 820ED is Swift's premium choice in porro prism birding binoculars. An 8.5x power is a great compromise between the classic debate of magnification, size and exit pupil diameter. With Audubon 8.5X44 BWCF 820ED Binoculars 820 ED, you'll have an exit pupil diameter of 5.1mm, great enough for viewing in nearly all birding situations, and a very wide 8.2? angle of view for an 8.5 magnification binocular. This Swift 8.5x44mm ED model is equipped with extra-low dispersion glass for extremely high contrast, resolution and sharpness across the entire viewing area.
