Focusing In On Best Price Binoculars
When buying binoculars, be it for hunting, birding, astronomy or sports viewing it will always pay to try out the pair you intend to buy in person. Visit your local high street dealer, and try out several pairs, but then go online to buy. The bargain prices are usually on the net.
There are 4 main factors to take into account when choosing a pair to suit you.
The first is the magnification. The most common magnification powers are 8x and 10x. 8x is generally good for most pursuits. Bear in mind though that as the magnification strength increases, the shake from the hands will become more noticeable, so choosing a pair with 10x and above may mean that you will also need a tripod to steady them.
The second factor to take into account is the size of the objective lenses. Measured in millimetres, these are the lenses furthest from your eyes, the big ones! As a general rule, the larger the objective lens, the brighter the image viewed through the binoculars will be.
It is usual to choose a lens size of around five times the magnification. So a 40 millimetre lens will be ideal for 8x magnification. If the 'bins' are to be used in low light conditions then a bigger lens size may be useful, but this will increase the size and weight of the binoculars.
Thirdly field of view should be considered.
Field of View means the width of the scene that can be viewed at 1,000 metres.
Generally speaking the lower the magnification, the wider the field of view. The recommended field of view is 10 metres at 1000 metres. This will suit most pastimes.
Lastly check out how close the binoculars will focus. This may sound a strange thing to consider, for an apparatus that helps us to look at distant objects, but birdwatchers for instance may also enjoy taking a close look at butterflies and insects. As lens manufacture has improved, it is now possible to buy binoculars that can focus at 3 Metres or less.
Bear the above in mind when deciding which pair will suit you best, these are the most important factors.
Happy Viewing
