Birding binoculars should have certain features. It can be difficult to find a pair with all of the things birders like. Although many stores sell some models, most of these have only a few of the important features.
The body of the optical equipment must be armored. If you slip on a rock and fall to the ground, unarmored optics can be ruined immediately. Lightweight pairs are more comfortable. A morning in the field with a heavy pair is likely to cause neck or shoulder pain.
Some kinds of birds can only be distinguished by very small markings. For this reason, it can be important to look at a bird through binoculars when it is only a few feet away. Close focus of about 5 or even 4 feet is a good feature.
Many birds hope out of sight as they forage in the canopy. They may do this in a single hop. A wider field of view makes it easier to track a quickly moving bird.
With any optical device, the bigger the front lens, the more light gets in, and the better one can see. But also, the greater the magnification, the less light gets in. The lens size in millimeters should be at least 5 time greater than the magnification. For example, 7x35 is a good type because they have a magnification of 7x and a lens size of 35mm. 7x28 is a bit too small for the level of magnification. 8x42 is a popular type.
Multi-coating on all glass surfaces that touch air is good. This collects more light, for a brighter image. It also reduces fuzziness that can come from scattering of light as it move between air and glass. Optical equipment can get fogged inside up if it is dropped in water, exposed to rain, drenched by dew, or even working if humid conditions. For this reason, waterproof binoculars are very important.
If one does not know where to shop, it can be difficult to find optics with all of these qualities. Just popping into the closest store is not likely to yield results.
