A binocular is a fantastic tool for getting closer to nature. We have teamed up with Viking Optical based in Halesworth to offer you their full range of high quality optic products. Although our online shop details 4 products from the Viking range you can buy any of the Viking products through us and support Suffolk’ wildlife at the same time. Please contact Michael Strand on 01473 890089 should this be of interest. Which one you buy will involve a fair degree of personal preference rather than science, but here are some pointers to help you make a choice.
Magnification
In general, binoculars best suited to watching wildlife and birds do not have extremely high magnification. This is because big magnifications require a lot of light to work. Lots of light needs huge objective lenses, which would render the binocular impractical in terms of portability. In addition, high magnification makes it very hard to hold the image steady.
So, an 8x or 10x magnification is the best compromise between power and practicality. If you think of looking at an object with your naked eye as 1x, then an 8x binocular would make the image eight times bigger than your naked eye.
If you mostly birdwatch in open country and/or looking across large stretches of water, you may want the extra magnification of a 10x. However, if you mostly birdwatch in woodland, at fairly close quarters, and/or like to be out when the light may be poorer (dawn and dusk for example), you would be best to opt for an 8x model.
Brightness
When trying to identify wildlife, it is helpful to have as much light and colour as possible. A quick indication of brightness can be gained by dividing the diameter of the objective lens by the magnification.
For example, an 8x42 binocular would have a brightness score of 5.25 (42 divided by 8), whereas a 10 x 25 would have a score of 2.5 (25 divided by 10).
More expensive models also increase their brightness by adding sophisticated coatings to the lenses, and by using very expensive and highly engineered glass.
