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.
Sometimes it is necessary to see minute features on a bird that is a few feet away. The ability to focus 5 or 4 feet away is a great advantage to the birder.
A wide field of view is also nice. Lots of birds jump around a lot. They can jump out of a small field of view in one hop. Having a wide one makes it less likely they will jump out of sight.
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.
All glass-to-air surfaces should be multi-coated. This enhances light gathering for a brighter image. It also decreases light scattering that can make the image more fuzzy. Waterproofing is also a must. Even if one does not go out in the rain, dew drops can get optical equipment really wet when chasing birds through the bushes.
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.
