If you can’t see your objective, you can’t meet it. CMC Government Supply carries some of the most popular brands and sizes of binoculars to help bring your target into focus. When selecting binoculars, CMC Government Supply recommends you have in mind your purpose for their use and educate yourself a little about optics. To make a selection, you will have to balance some factors, such as your intended use, skills and the power of the binocular. Below, we’ve included a few basics to help you in making the right selection for you.
THE BASICS ON BINOCULARS – MAGNIFICATION AND OBJECTIVE LENS DIAMETER
Although they come in all sizes from compact to full-size to suit different purposes, binoculars are primarily described/identified by their magnification and objective lens diameter using the format “magnification x objective lens diameter” (e.g., 8x42).
Magnification is the power multiplier for how close the item will appear as compared to the naked eye. Note that binoculars with magnification greater than 10 amplify the movements of your hands and body, making steady viewing and image clarity more difficult.
Objective Lens Diameter is the measurement of the diameter of the objective lens in millimeters. The objective lens is the lens farthest from your eyes. The objective lens diameter determines how much light the binoculars can gather, which has a direct relationship to the brightness of the view through the lenses, especially in low-light conditions. Remember to keep in mind your intended purpose, since studying the full moon would be more comfortable with lower brightness, while studying wildlife at dusk would require higher brightness.
Binoculars marked 7 x 42 or 8 x 42 are great for all-round general-purpose use. In general, the 7x and 8x binoculars are the most used in stadium sports, while the 2x-5x power binoculars are more intended for theater viewing or in night vision capacities. Due to the magnification of the movement of your hands and body, the 10x magnification binoculars are about the largest you want to use without having a stabilizing base, such as a tripod.
