NL Pure 8x42 Binoculars

The NL Pure 8x42 is a green 8x binocular whose enormous field of view lets you completely immerse yourself in nature, even during the late hours of the night.

What magnification and field of view does it have?

It magnifies 8x and shows 477 ft at 1,000 yds (9.1°), with a 69° apparent field of view. Magnification is the factor by which an object appears closer than its actual distance: the higher the magnification, the closer the object seems, but the smaller the field of view. Field of view is the size of the image section you can see through the optics, given in metres at 1,000 m, feet at 1,000 yards, or as an angle in degrees. Binoculars have a large field of view, so you can see a wide area. Spotting scopes have a higher magnification, which makes the field of view much smaller, but you can see more detail.

How well does it work in low light?

It has a 42 mm objective lens, 91% light transmission and a twilight factor of 18.3 (ISO 14132-1). The objective lens diameter sets how much light can enter the optics, which makes it a key factor in twilight performance. The bigger the objective lens, the more light it captures, and the darker the surroundings, the larger the objective lens needs to be.

How close can it focus?

It focuses as close as 6.6 ft. The shortest focusing distance is how close an object can be and still be seen clearly; between this value and infinity, you can focus the image.
