What do the numbers on the binoculars mean?
A high-quality set of binoculars offers the perfect opportunity to get a much closer view on the action, whether this might be viewing wildlife or sporting events. Binoculars come with a wide range of features relating to magnification and image quality, which generally means there is a wide range of binoculars on the market which will need to be matched to a particular application. If however you are able to appreciate the main aspects of the binoculars, then it will be much easier process for searching a specific model for use in a particular activity.
Here are some of the main aspects that relate to the numbers on the binoculars:
Basics of Magnification
Firstly the magnification of a set of binoculars is likely to be the first number in the series, which for instance if the binoculars are marked at 10 x 40, this essentially means the magnification strength is 10 times. Basically, this means that a person, place, or object, will seem to be at least 10 times nearer to your actual position.
If you do have a pair of binoculars with a magnification setting that is higher, this will of course make an object in the distance seem nearer, but it is often the case that the viewable field of vision will become smaller and the object will seem to shake more and offer a lower image quality. In a lot of cases the magnification strength is likely to be in the region of 7 times and 10 times. If you aren't going to be that far from a particular object, then it's often beneficial to use a set of binoculars with a lower magnification setting.
Basics of Aperture
A further point to consider is the aperture, which generally relates to the glass lens that is fitted on the front end of the binoculars. The aperture, which is calculated in millimeters, is often the second figure noted on the binoculars. For instance, if the strength of binoculars is marked with 10 x 40, then the 40 would relate to the size in diameter of the lens.
