What to Look for When Buying Binoculars

A thoughtful and useful gift for the nature enthusiast or season-ticket holder on your holiday shopping list is a set of binoculars.

Binoculars Buying Guide

Binoculars are two identical telescopes ganged together so that a person can look through them with both eyes simultaneously, providing a three-dimensional image similar to what would be seen without the use of binoculars. 

Fast Glass

Zoom lenses have become increasingly popular over the years for a number of reasons, including convenience (less lost time swapping lenses and in turn less chance of getting dust on the camera sensor and/or missing the shot altogether), weight (one slightlier heavier zoom can replace two or three slightly lighter but collectively heavier lenses) and slimmer camera bags (have you flown with carry-on baggage lately?). 

Binoculars

Everyone likes to get gifts, but some gifts are better than others. Sure, you pretend to like the malodorous cologne or the ugly sweater, but then they get tucked away somewhere until they eventually get thrown away. But binoculars make great gifts because everyone can use them and they can last a lifetime. Depending on one’s needs, decent binoculars can be had for less than $50 or they can cost several thousand dollars. There’s something for everyone.
