Binoculars are normally identified by two numbers. The first number is the magnification and the second number is the diameter of the objective lens in millimeters (mm). For example, 7×35 means the binocular magnifies objects 7 times and the objective lens is 35 mm in diameter. A 10×50 binocular magnifies objects 10 times and has an objective lens diameter of 50mm. • Magnification: 8X • Objective Lens Diameter: 28mm • Focus System: Center • Prism Type: Roof • F.O.V.
