Find Your Fit: How to Buy the Right Binoculars
Magnification
Since some binoculars are to see distant images, one of the fundamental aspects of your choice are magnification. The more increases our binoculars have, the farther we can see things clearly. Normal use usually requires binoculars from 6 to 10 magnifications, being the most powerful higher capacity, but with the risk of feeling more vibrations by holding them by hand.
In this case, the use of a tripod or stabilizer model that put a little extra firmness on the product is recommended. In any case, as important as the increases is the breadth of the field, which also allows us to define the visible area of the binoculars. This amplitude is measured in degrees and marks the range over which we will be able to look or see ahead.
Obviously, this amplitude is also related to distance, so that, the greater the number of increases, the greater the amplitude of the field we have already mentioned.
Vision and Brightness
When it comes to using binoculars, the ambient light conditions are essential to ensure adequate vision. Depending on the use we are going to give, night or day, it is convenient to choose a model with adequate brightness.
Mainly because a lower brightness than necessary leads us to see nothing in low light conditions, while if we opt for a high luminosity model, it can dazzle us in full sun situations. The luminosity is measured at different levels, based on a factor related to the optics of the binoculars.
The low brightness is for binoculars with factor 3.5 or lower, while the high brightness is for binoculars with factor 6 or higher. In any case and to start you, there are good and economical models of binoculars suitable for normal lighting conditions that are more than enough.
Quality
Although we have talked about numerical patterns of luminosity, almost as important as these elements is the level of quality of the optics and materials used in these products.
When we talk about binoculars we are talking about high precision optical elements whose quality is the key to obtaining a good result and in which it is worth leaving aside how much the product costs in favor of higher quality.
This point is so important that, if the optics are of good quality, the patterns indicated above for the different elements have a better performance than those of other products with better nominal standards, but with lower quality in their manufacture.
