Terrific optics


It's amazing that it's possible to buy such binoculars so cheaply. Images are bright, contrasty, and clear. My only criticism is that the first pair I received soon busted loose a prism. This was really an appalling lapse in quality control. However,...

Great optics

In first pair I purchased a prism soon broke loose

Super optics


I'll match the Swift 820 ED's against any glass that is out there for optical quality.

Fittings are cheesy and waterproofing yet to be tested

Zeiss-like views for under $300!

Clear and bright; waterproof; good price

A superb pair of binoculars


First of all I have the non-ED, "extra dispersal" version of this binocular. I have had my Swift Audubon 820 for over 3 years and have been very pleased with it. I work as a wildlife biologist and I take it everywhere. They work well in all kinds of...

Super features and reasonable priced

Not as compact as a roof prism

Product Specifications

Designed based on specifications gleaned from a Swift survey of the world's leading ornithologists, the Swift Audubon binoculars have become famous worldwide for superior performance and dependability. The 820 Swift Audubon has been rated "best buy" by Cornell Laboratory of Ornithology, Better View Desired, and the English publication, British Birds. They are 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 under 10 ft. The rubber-coated body is made of magnesium to reduce weight and is sealed to make the binoculars waterproof. Padded hard case and comfortable broad woven neck strap included.
