Tech Talk
Objective Lens: The diameter of the objective or front lens. The larger the objective lens, the more light that enters the binocular, and the brighter the image. Field of View (F.O.V.): The side-to-side measurement of the circular viewing field or subject area. It is defined by the width in feet or meters of the area visible at 1000 yards or meters. A wide angle binocular features a wide field of view and is better for following action. Generally, the higher the magnification, the narrower the field of view. Roof Prism System: In roof prism binoculars the prisms overlap closely, allowing the objective lenses to line up directly with the eyepiece. The result is a slim, stream-lined shape in which the lenses and prisms are in a straight line. |
