Description
National Geographic 10x42mm Single Bridge Binocular Black UG4038
The NatGeo Binocular 10x42mm SingleBridge are versatile Roof binoculars with superb characteristics suited to fulfil the most demanding outdoor needs. Its high-quality craftsmanship bundles many desirable features together.
The binoculars have BaK-4 prisms that are fully multi-coated. This allows for color fidelity and high contrast. The objective cap system allows for quick opening and closing, and the caps can be completely removed without any difficulty. Twist-up eyecups with 16.9mm eye relief adapt the binoculars easily to observers with or without spectacles. Diopter compensation for achieving proper focus for each eye is standard. Furthermore, the product is waterproof and purged with an inert gas to create a fog proof internal environment. Lastly, a tripod adapter thread is integrated.
The Bak4 glasses have a rounded exit pupil. This results in better light transmission and sharper images than the more usual BK7 glasses, which have a square-shaped exit pupil. Similarly, BK-4 prisms produce acceptable images, but their images are more rounded than in BAK-4 prisms.
BAK4 stand for barium crown glass and is the best material for making prisms. It has a higher refractive index and lower refraction than other materials, which makes it transmit light better without losing luminosity due to internal reflections within the device. Hence, from the start, know that this product offers some exceptional quality features!

If you need more time and information in order to make a selection from our premium products, take a few moments to familiarise yourself with the basics of how binoculars work.
HOW YOU CHOOSE
To begin with, a telescope or spotting scope may be more suitable for observing objects close up (meaning, bringing far objects really close). For general observation, a pair of binoculars is perfect.
In general, there are two types of binoculars, namely the older and original Porro Prism design (named after its inventor Ignacio Porro, who designed this prism system around 1850) and the more modern Roof Prism design. In order to choose your binoculars (e.g., selecting by the type, magnification strength and lens size) it may be useful to consult this overview.
The magnification power of your binoculars has a significant impact on the performance. If you have a more powerful pair, you “can get closer to the objects” you are looking at. However, the image will be smaller also. Reduce the power if you want a larger image within your visual field.
There is some variance within a single zoom class of field of vision. Hence people usually look for the 10 power Binoculars with the greatest field of view. While a broader field of view is important to some, the outskirts is unimportant to many.
There are many factors to consider, such as layout/optical technology (including types, brand and quality of optics, such as the lens type and prism type e.g. BK-4, Bak4, BAK7, SP, AK, and their coatings), the magnification/power rating, minimum focus distance (generally about 2.5 meters), the focusing mechanism (individual, focus free, or center), the housing materials, coatings and finishes such as rubberising or waterproofing.
