 Steiner BinocularsThere are several variables you need to balance when selecting the best binoculars for you: Magnification: Binoculars specifications include two numbers, such as 8 x 25. The first number is the magnification or power, indicating that the object you are looking at appears 8 times larger than when viewed with the naked eye. High power is good, but over 10 power it becomes hard to hold the binoculars steady enough. The more magnification the smaller the area you can see (smaller field of view). Light gathering ability: The second number is the diameter of the objective lens (the one furthest from your eye) in millimeters – 25mm in our example. The larger the objective lens, the more light enters the binoculars giving a brighter, sharper image. Larger objective lenses are better in low light conditions such as dawn and dusk. Size and weight: These relate to the light-gathering ability, materials and the type of prism system. Survivability: Binoculars can be damaged by scratching the lens, entry of water, dirt and by shocks. Better binoculars have seals to keep out contaminants while the best field and marine models have o-ring seals and are filled with nitrogen. This also stops interior fogging due to changes in temperature or humidity. Rubber armoured binoculars absorb shocks, protect from the elements, and provide grip. Focus: Several models of binoculars are focus free with the focus on infinity. These do not normally focus on close objects well and lower priced models lack adjustment for individual eye strengths. For viewing of birds and other small wildlife make sure your binoculars can close focus. Special features: Some binoculars have an integral compass so sightings can be taken while viewing distant objects. Price and brand: There is a wide range in price and performance, even between what might appear to be the same specifications. Design, the quality of glass and other materials, and the number, polish and coating of lenses determine the optical performance. The world’s best binoculars are made in Germany or Austria. |
