Like all Action Extreme Binoculars, the 12x50 model is built on an all-metal chassis with all optical components installed in a lightweight polycarbonate shell. The Eco-Glass lens system provides bright and tremendously clear images, while the streamlined Porro prism body is rubber coated for a non-slip grip wet or dry. The unique click-stop, twist-out eyecup design delivers both long eye relief and variable eye relief to customize the binocular to your eyes with or without glasses. A large-size all around performer, the new Action Extreme ATB 12x50 has a 288 feet field of view at 1, 000 yards - an impressive figure for a twelve-power binocular.

Angle of View / Apparent Angle of View:

*

The Angle of View is the angle between the left and right edges of the field of view at 1000 yards from the binoculars point of view. The Apparent Angle of View is this same angle with the binoculars magnification figured in, the Apparent is simply the ( magnification x Angle of View) . For a 10x magnification and a 5° Angle of View the Apparent would be 50° . This is directly related to the Field of View, but is often used to compare binoculars.

Tips: The Angle of View is just another way to express the Field of View. The higher the magnification the smaller the Angle of View. Here is a picture describing Angle of view
