Binoculars are marvelous tools, but the more you want to learn about them, the more technical and confusing they seem to get. They are an absolute must for some activities so, without being overly technical, here is a brief and simple guide to what types may be considered best for certain tasks:
Most people are aware of the standard types of binoculars known as ‘opera glasses’ specifically designed for theatre use. However, if you want something a bit more robust, or are watching an outdoor performance, then standard binoculars of about 6×30 may be a good bet.
If you are watching bird-life in woods, a wide view and a strong image is very important, especially from compact binoculars. 6×30 is good for looking around woods, 7×35 is good for ‘all-round field use’, and 8×35 or 9×35 is the best bet for looking at birds of prey over a longer distance. Bird-watchers may also want to consider the binoculars‘ ability in reduced light.
Astronomy traditionally is done with telescopes placed on tripods. However, when using binoculars, no tripod is necessary, so it is important to choose binoculars with a magnification that can easily be held steady, typically 8x or below. Also, as much light as possible is needed, so choose the largest objective lens diameter that you can comfortably carry; 7×50 to 9×63 may be just the job.
