What Is the Difference Between 10×50 and 12×50 Binoculars?
Binoculars are some of the most commonly used optical instruments. Usually, the devices are handheld and are designed to provide a magnified stereoscopic view of distant objects. A binocular has two telescopes, which are mounted on a single frame.
In some devices, a single thumbwheel can is used to adjust the focus of both telescopes simultaneously. Some of them may allow you to control the focus separately to ensure you get varying characteristics in both telescopes.
Just like tripods, you may experience some confusion when shopping for binoculars. At first glance, they may look similar, but they vary in terms of size, type, and features.
What’s the Difference Between Magnification Power and Objective Lens?
One of the easiest ways to identify the ideal binocular for different uses is their description. For example, you may find 10×50 and 12×50 binoculars. The first number represents the magnification power of the optical tools.
A 10×50 device will bring images 10 times closer than when viewing them using your naked eyes. It may seem like a higher number can translate to better images. However, this isn’t necessarily the case. This is because high magnification makes it harder for users to hold images steady in view.
On the other hand, a 12×50 means an object will be 12 times closer. Higher magnification is recommended if you are stationary and when viewing small objects at a great distance. If you intend to use your binoculars while moving or for quick focusing, use devices with low magnification.
The second number represents the size of the front lens. For example, 10×50 and 12×50 binoculars have a diameter of 50 millimeters. The larger the lens, the more the light the instruments can let in. Large lenses are ideal for dark environments.
Some of the main drawbacks of large lenses include making binoculars larger and heavier. If you carry heavy items, consider using binoculars will smaller lenses as you can hold them steady without having to brace your arms.
What are the Main Types of Binoculars?
Although the optical instruments have similar basic lenses, they vary in many ways. They are classified into two broad categories: Porro prism and roof.
Porro prism types are the most common in the market. Their optical path is bent like the letter Z. As a result, the images from the objective lens are reflected by two prisms. Also, this gives the devices their unique shape, where objective lenses are wider than eyepiece lenses.
Some of the reasons for the popularity of Porro prism binoculars include producing clear images and ease of manufacture. However, most of them are heavy and large, and this can be inconvenient for some users.
For roof binoculars, objective and eyepiece lenses are in a straight line. The feature makes it hard for users to get crisp, clear images. Some people prefer the roof devices due to their ergonomic design and their ability to handle the higher impact.
Other advantages of the design include the fact that they are compatible and ideal for traveling. As a result, royal binoculars tend to more expensive than Porro prism pairs.
