A lot of people find buying binoculars confusing. It is important to understand numbers like 6x30 when you go out to make a purchase. You will also need to be able to keep in mind any special features or any of the specialized types like night binoculars or marine binoculars. The most important thing to making the best choice is to consider how you intend to use them, and then everything else should come together nicely.

Magnification and lens diameter are by far the biggest things that you will need to think about when you are looking at binoculars. A number like 6x30 will be clearly marked on the binoculars to let you know what this is. Magnification is determined by the number that comes first and that is nothing more than how many times closer an object will seem. Lens diameter will be the number you see second and it is shown in millimeters. The field of view will be bigger if you have a bigger lens diameter.Unfortunately it’s not simply a matter of buying the binoculars that have largest numbers, that would be much too simple. It is difficult to pick up moving objects if you have a high degree of magnification, so that could be a problem for some uses. Having a big lens diameter will allow you an excellent field of view but it comes at the price of bulky and heavy binoculars, not a good idea if you are going to be carrying them a long way.

The brightness of a pair of binoculars is determined by the size of the exit pupil and this is another bigthing that will need to be considered. If you lens diameter and divide it by the magnification you will figure out the size of the exit pupil. The larger this number is the more light will reach your eye. This can be a problem in bright sunshine but is almost a requirement if you are using your binoculars at night. For use at night you are going to need an exit pupil that is at least 7 mm. On the other hand if you plan to use them in bright sunshine 3 mm is probably good, 5 mm is a good middle ground for a wide variety of uses.

There are a couple of other things that you are going to have to consider but they are for the most part a matter of personal preference. Considerations like how you focus the binoculars or what type of prism is used can be a big deal to some people while other people really won’t care. You will want to keep in mind any of the specialized types of binoculars that may need like digital binoculars or stabilized binoculars. Having how you are planning to use the binoculars in mind will help to make certain that you make the right selection for your needs.
