Description

National Geographic 8X42mm Porro Binocular UG4028

The NatGeo Binocular 8X42mm Porro features some excellent characteristics such as Bak-4 prisms and fully multi-coated prisms to provide great color fidelity and high contrast. Twist-up eye cups to cater to observers with or without glasses and quick and easy opening and closing objective caps to protect the objective lenses.

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!

The field of optics can be complex and to choose your device can be tricky, so read on if you need further support to select a binocular. However, the NatGeo Binocular 8X42mm Porro is a good stop as it is versatile and practical, suited to a wide range of applications and is affordable.

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.
