Technical terms
What do
the numbers mean?
The numbers on a pair of 7x42 binoculars for example, describe them as follows:
"7x" means that the object in view appears 7 times larger than when
visualised with the naked eye. "42" is the size or diameter of the
front (object) lens, expressed in millimetres. A larger diameter lets in more
light and makes the binoculars better in poor light conditions.
Field
of view
Field of view is the extent of the view you have through the glasses. Field of
view is expressed at a range of 1000 meters. The greater the magnification, the
narrower the field of view. Higher magnification and narrower field of view,
make binoculars harder to hold still without support.
