What Is 12x50 Binocular ?
A 12x50 binocular is a type of binoculars that has a magnification power of 12x and an objective lens diameter of 50mm. This means that the image seen through the binoculars will appear 12 times closer than it would with the naked eye, and the objective lens will gather more light, resulting in a brighter and clearer image. The 12x magnification is suitable for long-distance viewing, such as bird watching or stargazing, while the 50mm objective lens provides a wide field of view and good low-light performance. The binoculars may also have additional features such as waterproofing, anti-fogging, and image stabilization.
1、 Magnification
What is 12x50 binocular? The 12x50 binocular is a type of binocular that has a magnification power of 12x and an objective lens diameter of 50mm. This means that the binocular can magnify an object up to 12 times its original size and has a larger objective lens diameter that allows more light to enter the binocular, resulting in brighter and clearer images.
The 12x50 binocular is a popular choice among bird watchers, hunters, and outdoor enthusiasts who require a high magnification power and a larger objective lens diameter for better image quality. The 12x magnification power allows users to see distant objects with great detail, while the 50mm objective lens diameter provides a wider field of view and brighter images, even in low light conditions.
However, it is important to note that the higher the magnification power, the more difficult it is to keep the image steady. This means that the 12x50 binocular may require the use of a tripod or other stabilizing device to prevent image shake and ensure a clear view.
Overall, the 12x50 binocular is a great choice for those who require a high magnification power and a larger objective lens diameter for better image quality. However, it is important to consider the potential need for a stabilizing device and to choose a binocular that fits your specific needs and preferences.
2、 Objective lens diameter
What is 12x50 binocular? The 12x50 binocular is a type of binocular that has a magnification power of 12x and an objective lens diameter of 50mm. The magnification power of 12x means that the image viewed through the binoculars will appear 12 times closer than it would with the naked eye. The objective lens diameter of 50mm refers to the size of the front lenses of the binoculars. The larger the objective lens diameter, the more light the binoculars can gather, resulting in brighter and clearer images.
The 12x50 binocular is a popular choice for birdwatching, hunting, and other outdoor activities. Its high magnification power allows for detailed observation of distant objects, while the large objective lens diameter provides a bright and clear image even in low light conditions. The binoculars are also relatively compact and lightweight, making them easy to carry around.
However, it is important to note that the 12x magnification power can make the image appear shaky or unstable if the binoculars are not held steady. Additionally, the larger objective lens diameter can make the binoculars heavier and bulkier than other models with smaller objective lenses.
Overall, the 12x50 binocular is a versatile and reliable option for outdoor enthusiasts who require high magnification and clear images.
3、 Field of view
What is 12x50 binocular field of view? The field of view of a binocular refers to the width of the area that can be seen through the lenses. In the case of a 12x50 binocular, the field of view is typically around 5-6 degrees, which means that you can see a relatively wide area when looking through the binoculars.
However, it's important to note that the field of view can vary depending on the specific model of binoculars that you're using. Some binoculars may have a wider or narrower field of view, depending on factors such as the size of the lenses, the magnification power, and the quality of the optics.
In addition to the field of view, there are other factors to consider when choosing a binocular, such as the level of magnification, the quality of the lenses, and the overall durability and construction of the binoculars. It's also important to consider your specific needs and intended use for the binoculars, whether you're using them for birdwatching, hiking, or other outdoor activities.
Overall, a 12x50 binocular can be a great choice for those who want a relatively wide field of view and a high level of magnification. However, it's important to do your research and choose a high-quality pair of binoculars that will meet your specific needs and provide clear, sharp images.
4、 Exit pupil
What is 12x50 binocular Exit Pupil?
The exit pupil of a binocular refers to the diameter of the beam of light that exits the eyepiece and enters the eye. It is an important factor to consider when choosing a binocular as it determines the amount of light that enters the eye and affects the brightness and clarity of the image.
In the case of a 12x50 binocular, the exit pupil can be calculated by dividing the objective lens diameter (50mm) by the magnification (12x), which gives an exit pupil of 4.17mm. This means that the beam of light that enters the eye is 4.17mm in diameter.
A larger exit pupil allows more light to enter the eye, resulting in a brighter image, especially in low light conditions. However, the human eye can only dilate up to a certain size, typically around 7mm, so an exit pupil larger than this will not provide any additional benefit.
In summary, a 12x50 binocular has an exit pupil of 4.17mm, which is a good size for general use and provides a bright and clear image. However, if you plan to use the binocular in low light conditions, you may want to consider a larger exit pupil or a binocular with a lower magnification.
