Simply put, the field of view denotes the scope or width of the area you can view through the lenses. For stargazing, consider a magnification between 10x to 20x and an objective lens between 50mm and 80mm, depending on how narrow you want the field of view to be. If, however, your goal is to have a closer and narrower view to observe, for instance, deer or small animals from a safe distance, a 10x magnification can give you an extra boost. They’re lightweight and have strong enough magnification for most users, while providing a steady and wide image. Bear in mind that larger objective lenses (42 mm or more) also tend to be found in heavier, sometimes unwieldy binoculars.īinoculars with a magnification between 6x to 8x and objective lenses between 30 mm and 42 mm are generally recommended for classic outdoor activities such as birding and hunting, and they'll also work well for concerts and sports events. Bigger lenses mean more light, and consequently more effectiveness in low light settings. The number specifies the diameter of the lens in millimeters. This is the glass at the end of the binoculars that captures light. The second number refers to objective lenses. Binoculars with greater magnification let you see targets that are far away, though they also provide a narrower field of view. An 8x lens would seem to make the object 8 times larger, whereas an 10x would make it 10 times larger.
Ocular lenses are located within the eyepiece, and the number lets you know the image magnification - that is, how much the lens appears to enlarge distant objects. The first number (8x in the pair of Celestrons mentioned above) refers to the ocular lens.
The numbers refer to two different types of lenses, which together help you see objects that are far away, in varying degrees of light. For example, what does the "8x42" in the Celestron Outland X 8x42 binoculars mean? Best binoculars buying guideīefore you start shopping, it’s important to understand the meaning of the numbers used in binoculars' model names. In fact, there are plenty of great affordable options for beginners and casual wildlife enthusiasts comparable with models that cost twice or three times as much. Unless you’re a professional, you don’t need to invest thousands of dollars to get a good pair of binoculars. Options range from basic binoculars costing less than $100 to professional-grade top-of-the-line devices that can cost over $2,000. However, choosing the right pair of binoculars can be a daunting task considering the wide variety of models on the market. A good pair of binoculars is essential for explorers who are passionate about truly seeing the great outdoors while birding, hiking, hunting, viewing wildlife, scouting, camping and stargazing.
