What Does 12×50 Mean in Binoculars? Significant figures to keep in view

Binoculars are a useful tool for observing distant objects in detail. They are often used for birdwatching, hiking, hunting, and other outdoor activities.

What Does 12x50 Mean in Binoculars

 we will discuss in this article the meaning of 12×50 in binoculars and what it signifies.

1. Magnification and Objective Lens Diameter

The numbers in a binocular’s specification denote its magnification and objective lens diameter, respectively.

Magnification refers to how much larger an object appears when viewed through the binoculars compared to when it is viewed with the naked eye. Objective lens diameter refers to the diameter of the front lenses of the binoculars.

In the case of “12×50”, the “12” represents the magnification of the binoculars. This means that the object being viewed will appear 12 times closer than it would if viewed with the naked eye.

The “50” represents the objective lens diameter, which is measured in millimeters. In this case, the objective lenses are 50 millimeters in diameter.

2. What is the significance of these numbers?

The magnification and objective lens diameter are important factors to consider when choosing binoculars. A higher magnification allows for a closer view of distant objects, but it also reduces the field of view and makes the image shakier and more difficult to focus.

A larger objective lens diameter allows for more light to enter the binoculars, resulting in a brighter image. In the case of 12×50 binoculars, the magnification of 12 is a good balance between a close view and a steady image.

It is not too high, so the image will not be too shaky, but it is high enough to see distant objects in detail. The objective lens diameter of 50mm is large enough to provide a bright and clear image, even in low-light conditions.

3. Other factors to consider when choosing binoculars

While the magnification and objective lens diameter is important, there are other factors to consider when choosing binoculars. These include the type of prism used, the quality of the optics, and the durability of the binoculars.

There are two types of prisms used in binoculars: roof prisms and porro prisms. Roof prisms are more compact and durable, but they are also more expensive. Porro prisms are less expensive but are bulkier and less durable.

The quality of the optics is also important. High-quality optics will produce a clear, sharp image with minimal distortion, while lower quality optics may produce a dim or distorted image.

Finally, the durability of the binoculars is an important factor, especially if they will be used in rugged outdoor environments. Look for binoculars with a rugged, waterproof design and a strong, durable body.

Frequently Asked Questions

Is a 12×50 magnification good for binoculars?

It depends on your needs and intended use. A 12×50 magnification can be considered high-powered, so it may not be suitable for all users or situations. Consider factors such as the distance you’ll be viewing from and the level of detail you need to see.

What is the importance of the 50mm objective lens in 12×50 binoculars?

The 50mm objective lens in 12×50 binoculars helps to gather more light, resulting in a brighter and clearer image. This can be especially important in low-light conditions or when viewing objects from a distance.

Are there any downsides to 12×50 binoculars?

One potential downside to 12×50 binoculars is their weight and bulkiness. They may not be as portable or easy to carry as smaller binoculars. Additionally, the high magnification may make it more difficult to keep the image steady without the use of a tripod or other stabilization device.

What should I look for when buying binoculars?

When buying binoculars, consider factors such as the magnification, objective lens size, quality of optics, weight and size, type of prism, and any additional features such as waterproofing or image stabilization.


“12×50” in binoculars refers to the magnification and objective lens diameter, respectively. A magnification of 12 and an objective lens diameter of 50mm are a good balance between a close view and a steady image, and a bright, clear image even in low light conditions.
