Zoom binoculars: Features and functions to look for

When you're shopping for binoculars, especially zoom binoculars, you need to have a basic understanding of their uses, performance and features. Zoom binoculars are available from many manufacturers. Look for quality instruments from makers like Bushnell or Meade. These models will allow you the flexibility and ease of zeroing in on your viewing target at low magnification Then, with a quick adjustment, you can zoom in to see incredible detail at higher magnification.

Zoom binoculars specifications are usually expressed in a numeric format separated by an "x" -- for example, 10-30x50. The numbers to the left of the "x" mean that the zoom factor runs from 10 to 30 power. Power or magnification is measured against naked-eye sighting. 10-30x means that the object seen through the binoculars will appear to be 10 to 30 times closer than if seen with the naked eye. The number after the "x" is the diameter in millimeters of the lens at the end of the binocular tube, the objective. The larger the objective, the brighter the image will appear. Buy the largest objective you can afford -- a 70mm objective will deliver an image almost twice as bright as a 50mm lens. A larger objective will also perform better in low light conditions.

Reflection and glare can be a problem at higher magnifications. Lens coatings help reduce these by improving light throughput. Look for lenses with multi-coated or fully multi-coated lenses. They may be more expensive but will perform better. Internal fogging can also happen unless the tubes are nitrogen filled and well sealed. Zoom binoculars should have all the quality features of regular binoculars and are perfect for hunters, bird watchers and sporting enthusiasts alike.
