How Far Can You See With 20×50 Binoculars?
The first number used to describe the optics on a binoculars means that images will be 20 times closer than you can see them with your naked eyes. For example, if a target is 100 yards away, it’ll look as if its 5 yards away. On the other hand, the second number refers to the size of its objective lens, which is 50mm. With a pair of 20x50mm binoculars, far away objects will appear to be significantly closer, and you’ll be able to spot things that you otherwise wouldn’t be able to with the naked eye. However, the limit on how far you can see is still based on both terrain and the curvature of the Earth, so keep in mind you won’t be able to see forever!
The features make it suitable for some applications than others. One of the drawbacks of the high magnification power is that they may not be effective when focusing on objects at close range. The optical instruments have a close focusing distance of 45 feet.
Therefore, objects closer than 45 feet will appear blurry. If you opt for high magnification, you’ll not get clear pictures if your hands are shaking or your device is moving. Read on to learn more about the 20×50 binoculars and some insights when shopping for one.
Who Can Use 20×50 Binoculars?
High magnification binoculars are ideal for greater distances. It is also a perfect choice for people looking for a quality pair of long-range devices for casual use. For example, you can use them for nature viewing, birding, and hunting.
Also, if you intend to use them to enjoy a sports game from the nosebleed seats, these optics can offer better views. If you’re a beginner looking to buy your first long-range binoculars, the 20×50 binoculars are perfect choices.
Special Considerations When Buying 20×50 Binoculars
Other than the magnification power and the size of the objective lenses, there are several factors that you should consider before making the final decision. Here are some considerations:
The Coatings of your Binoculars
Binoculars have lens and prism coatings. The lens coatings are applied to lens surfaces and have many benefits. For example, they help to reduce glare and reflections, improve light transmission, and to produce vivid colors.
Eliminating reflections means you’ll get brighter and sharper images. You may find cheap coatings in the market, but they may not offer the quality you need for images. If the optics are coated, it means that at least one of the lenses have coatings.
If your device is multi-coated, it means several surfaces have coatings, or they have multiple layers of coatings. Lens coatings are effective across a wide spectrum of wavelengths and guarantee excellent performance.
On the other hand, prism coatings are used for complementing the lens coatings. They allow almost 100% of light through the prism, and this leads to brighter images. Some users cannot tell the difference between different types of prism coatings, but professionals may require them to ensure they get detailed images at a distance and in low light.
The Type of Prisms
Porro and roof prisms are the two types of prisms in the optical devices. The former was invented in the 1850s and revolutionized the world of binoculars. A few decades later, roof prisms were introduced.
Usually, devices with Porro prisms are cheaper than their counterparts as their manufacturing process is cheaper. They are commonly used in large binoculars used by astronomers. With time, roof prisms have become more popular. They allow manufacturers to make devices with a more streamlined appearance, and this makes them lighter.
