Designed based on specifications gleaned from a Swift survey of the world's leading ornithologist, the Swift Audubon binoculars have become famous worldwide for superior performance, dependability, and trusted amongst the most expert Birders.
Equipped with a 5-lens ocular system, BaK4 prisms, fully multi-coated optics, and pop and lock eyecups adding comfort for eyeglass wearers. The Swift Audubon produces crisp, high definition images to the outer edges of the wide field and close focuses to 12 ft. The rubber-coated body is made of magnesium to reduce weight and is sealed to make the binoculars waterproof.
Added to the patented features and world-renowned optical formula of the original 820 Swift Audubon is an ED (Extra-low Dispersion) lens. ED Glass provides an exceptional, precise color definition while promoting optimum resolution and sharpest possible images. It even further expands the viewing capabilities of fine optics.
