What Are The Most Powerful Binoculars You Can Buy?
The power of binoculars is seen in the clarity of images in dim light and over a long distance. To make powerful binoculars, manufacturers have gone for some that magnify objects up to 160X. However, this doesn’t mean that the binoculars with the highest magnification are the most powerful.
High magnification, coupled with a higher objective lens diameter, a higher field of view, a larger exit pupil, and good quality lenses make powerful binoculars.
For a long time, zoom binoculars have taken the space as the most powerful binoculars. These are binoculars with adjustable magnification. For instance, instead of the specs appearing as 20×40, it appears as 20-30×40. With zoom binoculars, you can adjust the magnification to fit different light conditions and different viewing distances.
Quality of Images
Although some zoom binoculars will promise power, some of them do not provide clear images. If, for instance, a pair of binoculars has a magnification of 180x, it needs an objective lens with a large diameter to match. This way, as you zoom, enough light gets into the binoculars for image clarity. Again, if the optics glasses are cheap quality plastic, the amount of light that gets in is limited, and the image appears distorted.
Granted, the most powerful is not necessarily a pair of zoom binoculars. However, this type of binoculars allows you to work in different light conditions.
Sunagor Mega Zoom 30-160×70
Sunagor sells this pair as the “world’s most powerful binoculars.” It sports a sliding zoom lever and a center focus knob, for fast zooming and focusing. In bright light conditions, you can zoom up to 160x and still get clear images. In dim light, you might need to lower the magnification for clear images.
To complement the high magnification, the binoculars feature premium quality multi-coated optics and BAK-4 prisms. Its rubber-armored body allows you to hold it steady when you are viewing distant objects.
Oberwerk XL Series
The Oberwerk XL series comes as a replacement for the Oberwerk BT series. The flagship packs 80x magnification with 100mm objective lens. The specs allow Oberwerk to magnify even under low light conditions. According to Oberwerk, the XL series features the latest optical technology to guarantee enough light gets into the binoculars for the clear images.
Shopping for Powerful Binoculars
There are many more binoculars that claim to be the most powerful in the world. When shopping, besides magnification and objective lens diameter, you should consider:
The field of view – This refers to how wide an image appears when you view it through a pair of binoculars. For instance, powerful binoculars night has a field of view of 113m at 1000m, which means that objects 1000m away will appear 113m wide. Binoculars with high magnification power allow you to get closer to the image – it, therefore, gives you only a small section of the image. For a wider image, choose binoculars with low magnification power.
Other factors include eye relief, prism type, exit pupil diameter, lens coatings, close focus distance, light transmission percentage, and the lens material, among others. You also need to consider other factors outside the power of binoculars, such as waterproofing, size, and durability.
