Binoculars reviews: Don't rely on them completely

If you're shopping for binoculars, reading binoculars reviews can be very helpful, but only to a point. Reading binoculars reviews cannot take the place of doing research on your own. It's important to learn about the various manufacturers and the features and functions they offer. Only then will you be able to make an informed purchasing decisions.

Although there are plenty of binoculars reviews available, they might just lead to confusion unless you understand the terms they discuss. For example, if you don't understand the terms "power" and "aperture," descriptions of these features, if mentioned in a review, won't mean much to you. Here is a short explanation of these qualities.

A number followed by an "x" usually expresses power or magnification. Aperture is usually expressed as a number following the "x." For example, the expression "10x50" means the binoculars have a magnification factor of 10 and an aperture of 50. If binoculars reviews don't explain this, it makes them pretty useless. A power of 10 means that the object seen through the instrument will appear to be 10 times closer than if seen with the naked eye. An aperture of 50 means that the diameter (usually expressed in millimeters) of the objective lens in the binoculars (the lens at the far end of the instrument) is 50 mm. The larger the aperture, the more light the lens can gather, and the more bright and high-contrast the image will be.

As you can see, binoculars reviews only provide part of the picture. To select the right instrument for your needs, you should take the time to gain a basic understanding of how binoculars and the optics inside them work.
