Bird Watching Binoculars - How They WorkCompact Or Standard BinocularsIf you do a lot of hiking or hunting where weight can be an issue, a quality compact model may work best for you.On the other hand, if you're not carrying a lot of extra gear, a standard pair of bird watching binoculars will always offer more features. Not only are they one of the most important pieces of gear for bird watching, they can be used for sporting events, theater/concerts, vacations, and camping. A quaility pair can last a lifetime. Always invest in the best pair you can afford. Understanding The NumbersWhen selecting a pair, you'll need to understand what the numbers mean. There are two numbers separated with an "x".The first number refers to the power or magnification. As an example let's say it is 7X35. The 7 means that the object appears seven times closer than you would see it without any help. The second number is the size of the objective lens measured in millimeters going across the lens. The size of the objective lens will determine how much light it can obtain for effective viewing. The higher the number, the larger the lens; in effect allowing more light to pass through thereby projecting a brighter image and viewing experience. The side-to-side measurement of the circular viewing field or subject area, is defined by the width in feet or meters of the area visible at 1000 yards or meters. Generally, the higher the magnification, the narrower the field of view. Digital Camera Binoculars:
Digital Camera Binoculars allow you to see the subject and capture a picture, enabling you to print copies or email them to friends and family from your computer.
An excellent choice for the avid bird watcher. These types of binoculars allow the backyard birder to enjoy the best of both worlds, at the price of just one piece of equipment. Not only are wild bird watchers able to experience birds close up, but now you're able to take pictures and create photo albums of all the birds you want to add to your life list. When digital cameras can't get close enough, these hybrids allow you to photograph exactly what you see through a binocular. You simply aim focus then press a button, and the digital camera automatically records the image. Types Of BinocularsThere are two basic types of binoculars: Porro prism and roof prism. You can tell them apart by the shape. Porro-prism: These have an angled design. When standing on their barrels they appear to form an M shape.Porros focus using an external focus wheel which, when turned, moves the eyepieces forward or backward along an external barrel. Roof-prism Binoculars: This design features two straight barrels, giving it an H shape. With this design the focusing mechanism is enclosed inside the binoculars and is adjusted with an external focusing knob or wheel. Roof-prisms cost more to manufacture and tend to be more expensive than porros, but roof prism types are not necessarily better than porro prism types. Quite often when comparing inexpensive, similarly priced, the porro prism is the better product. The advantages of roof prisms are: the narrower body shape is easier to handle; there are fewer external moving parts (this increases durability; they are generally water proof; and they produce an apparently larger image. One additional point - most binoculars today are built with the bird watcher in mind, making your choice much easier.
