Description
National Geographic 7x50mm Porro Binocular Black UG4021
The The NatGeo Binocular 7X50mm Porro have excellent optical characteristics. The green fully coated optics guarantee a decisively higher light transmission through the glass, thus increasing colour fidelity and contrast. Diopter compensation is standard with these models.
These binoculars are suitable for beginner birders or nature observers. Even on windy days, due to the magnification lying at the relatively lower end of the spectrum (7x), a stable image can be maintained. The 50 mm objective lenses gather enough brightness for observation even in twilight conditions.
FEATURES
- Porro binoculars with a large objective lens diameter
- Ideal for observations even in low light conditions
- Suitable for spectacle wearers thanks to diopter compensation and foldable eye cups
- Can be connected to a tripod for longer observations
- Easy to use and Durable

The The NatGeo Binocular 7X50mm Porro has a broader field of view than higher-end binoculars and this may come in handy in many applications.
The field of optics can be complex and to choose your device can be tricky. Nevertheless, take a few moments to read further and assist yourself in selecting one of our premium products.
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.
