Some of the best binoculars are wonderful pieces
of equipment that can enhance many of your daily
activities these activities will include
birding, action sports, hunting, and even
astronomy. Essentially, the best binoculars take
a distant image, enlarge it through the use of
lenses for viewing, all while remaining small and
light enough to be mobile.
3
The actual makeup of most binoculars is fairly
straightforward and simple. You have the lenses
at the end of the barrel called the objective
lens that gathers the light from the distant
image and focuses it on the lens closest to your
eyes for viewing. Your best binoculars are really
two small telescopes put side by side so that you
can view the desired image with both eyes instead
of just one. This imparts some measure of depth
of field, much more so than with a single scope.

When selecting a pair of bird watching binoculars
you will immediately find that two numbers are
used to describe their capability. These numbers
are often expressed as "6 X 30" or something
similar. Let's break the code so you will know
what these numbers mean. The first number refers
to the magnification power of the binoculars, or
in other words how many times the image is
magnified. So if the number is 6, that means that
the image that you view through the lens is
magnified 6 times its normal size. The second
number has to do with the size of the objective
lens at the end of the bird watching binoculars.
It's good to know this number because the larger
the diameter of the objective lens, usually the
more light will be let in for viewing the distant
image.
5
Now, let's put this information in use in the
real world. You may think that it's best to just
get the highest magnification that you can get so
as to end up with the best binoculars nothing is
further from the truth. At some point, hand
holding the binoculars will affect the clarity of
a highly magnified image and the resulting shake
will render the magnification benefits useless.
6
Generally speaking, anything above ten times
magnification should be mounted on a tripod
instead of handheld. So if you are planning to
use your best binoculars for activities that do
not allow you to be able to bring along a sturdy
tripod, you probably want to stay with a pair of
binoculars with 4 -7 times magnification.
7
As far as light gathering properties are
concerned, if you plan on using your best
binoculars in any kind of low light situation
whether indoors, or at times of day when there is
low available light outdoors, then you need to
have a large objective lens, usually 30 or above,
to make as much use of available light as
possible.
