Top Rated Bird Watching Binoculars

Binocular bird watching is a fascinating outdoor activity enjoyed by many individuals in their spare time. These bird watching group members prefer carrying long-lasting, light-weight and flexible focusing binoculars which enable them to target bird species of any size for observation. The key advantages of specific bird watching binoculars are their ability to magnify the small creatures at a distance and to allow a degree of stealth on the part of the watchers so that the animals are not frightened away. Although accomplished bird watchers are skilled at buying the perfect binoculars for the sport, there are a few factors beginners should consider in making their purchase.

Specifications of a Perfect Binocular

The fundamental features to be considered include magnification, objective size, prism type, focusing, and physical form factors.

Magnification:

Usually these specialized binoculars are available in the range of 7x-10x. An 8x binocular is regarded as the most suitable for the beginning bird watchers. Some other types include 7x35, 8x42, and 10x40. Although a 10x binocular enlarges an image more than a 7x one, it is heavy-duty and therefore difficult to carry. A lighter model is a better choice for newcomers to the sport.

Objective Size:

Objective size (also referred to as the diameter of the objective lens) is usually denoted by the number written next to the power of lens. For instance, an 8x42 binocular is comprised of a lens which measures 42 millimeters. The smallest binocular objective lens available is 30 millimeters.

Prism Type:

The two most popular brands of bird watching binoculars are the porro-prism binoculars and the roof-prism binoculars. Porro-prism binoculars are heavy-duty optical instruments while the roof-prism models are compact and lightweight. Of the two, the roof-prism binoculars are the more expensive. Porro-prism binoculars make use of two right-angled prisms placed in a barrel while a roof-prism uses five small prisms in a barrel. Porro-prism offers a more brilliant image and can focus at a close distance.

Focus Type:

The focus type for an ideal birding binocular should be center focus, which works perfectly for birds at a distance as well as those in close proximity.

Close Focus:

A perfect birding binocular must be capable of focusing on birds at a span as close as 15 feet or less. However, an ideal one may focus at a closer distance of around 10 feet. Close focus plays an important part in woodpecker bird watching and the observation of other species that will tolerate the close proximity of human beings.
