There are larger power binoculars available, and most higher power binoculars are usually the variable type, also known as zoom binoculars. A 20x – 80x zoom binocular, for instance, has a magnification range from 20 to 80 power. Objective lens: The objective lens (front lens) diameter is listed in millimeters. The larger the lens, the more light can enter the binocular and the brighter the image will be. However, binoculars with smaller lenses are more compact and portable. Field-of-

Zoom binoculars offer the user a range of magnifications. The zoom function can be operated by hand using a lever, or by switch when driven by a motor. Zoom systems vary by model. Waterproof binoculars and fog-proof binoculars should be nitrogen purged and O-ring sealed in order for their internal lenses to be truly resistant to fogging and/or water damage.

Focusing your binoculars: Most binoculars have a center focus wheel and an independent right diopter eyepiece to account for small differences in the strength of each eye. Please follow the steps below to focus properly: 1. Adjust the interpupillary distance. 2. Rotate the right eyepiece to its index mark and sight on a fixed distant object. 3. Cover the right objective (front) lens with your hand, then rotate the roll-down / twist-adjust eyecups central focusing wheel until the image in the

Others will not have a center focus wheel, and you must turn each eyepiece independently to focus. Never try and force an eyepiece if it was not designed to turn. This may seriously damage your binocular. Roll-Down Eyecups Your binoculars may be fitted with rubber eyecups designed to exclude extraneous light. If you wear eyeglasses, you may be able to roll-down the eyecups. Some binoculars are outfitted with twisting eyecups which raise and lower the eyecups. For eyeglass wearers, lowe
