A question that often arises is how important is cost? There is a fairly wide range of cost in birding binoculars, but keep in mind that cost might not be the most important factor.  The features and functions as mentioned above are the primary factors in choosing a pair of birding binoculars.

As you research which pair of binoculars is the best for you, an understanding of the basic features is important.  Here is a list and explanation of some of these basic features.

- Magnification:  Every pair of binoculars is labeled with two numbers.  The first number is the magnification.  For example 7 x 20, 8 x 32, 10 x 40, etc. are typical designations.  Most veteran birders suggest a magnification of between 7 – 10.

- Lens Width:  The second number (7 x 20, 8 x 32, 10 x 40, etc.) in the designation is the width of the front lens also known as the objective lens, in millimeters.  The higher the number the greater the amount of light and the brighter the image.  The larger the ratio between the magnification (1st number) and the lens width (2nd number) the greater the resolution.

- Field of View:  The field of view can be an important consideration.  As it will allow you to more easily find and track a particular bird or a couple of birds at one time.

- Lens Coating:  Some lens a have different lens coatings.  These help improve the color of the image as well as the amount of light.  Pink and purple coatings will help improve the color quality of the lens.  While a green coating will fade out the background and make the image of the bird standout.

- Size:  The size of the binocular is an important consideration.  The size needs to be comfortable and easily adjustable with a minimum amount of movement.
