10×50 vs 16×50-Comparison Factors
We will compare both 10×50 and 16×50 base on below factors
- Magnification
- Twilight factor
- Exit Pupil & Image Brightness
- Field of View
- Eye Relief
- Size and Weight
- Price
Magnification
The 10×50 binoculars magnify the image 10 times, while the 16×50 binoculars magnify the image 16 times. This means that the image seen through the 16×50 binoculars will appear larger and closer than that seen through the 10×50 binoculars.
One advantage of higher magnification is that it allows for more detail to be seen in the image.
This can be particularly useful for birdwatching or other nature observation, where the ability to see fine details can make a big difference.
However, higher magnification also comes with some disadvantages. One of the main disadvantages is that it can make the image more unstable, as even small movements can cause the image to shake and blur.
Note: Sometimes If you choose a higher magnification binocular such as 16×50, image stabilization technology becomes important. Image stabilization technology is designed to reduce the impact of movements on the image seen through the binoculars. This can make a big difference in the viewing experience, particularly when using higher magnification binoculars.
When considering the magnification of binoculars, it is important to also take into account the intended use of the binoculars.
For example, for general purpose use such as hiking or travel, a lower magnification may be more appropriate, as it can provide a wider field of view and greater image stability.
On the other hand, for specific uses such as astronomy or long-distance viewing, higher magnification may be necessary to see the desired level of detail.
Twilight factor
Twilight factor is a term used to describe the ability of a pair of binoculars to gather light in low-light conditions, such as at dawn or dusk. A higher twilight factor results in more details of the image at dawn and dusk
Twilight Factor is calculated by multiplying the magnification power of the binoculars by the diameter of the objective lens (the front lens). The resulting number is then squared, and that number’s square root is the twilight factor.
The twilight factor of the 10×50 binoculars is approximately 22.4 and the twilight factor of the 16×50 binoculars is approximately 28.3.
When comparing 10×50 and 16×50 binoculars, the difference in their twilight factor is primarily due to the diameter of their objective lens.
Twilight factor is important for low-light conditions because it directly affects the brightness and detail of the image seen through the binoculars.
A higher twilight factor means that more light can be gathered by the binoculars, resulting in a brighter and clearer image. This can be particularly important for certain activities, such as astronomy or hunting, where the ability to see fine details in low-light conditions can be crucial.
For example, in astronomy, a higher twilight factor can make it easier to see faint stars or other celestial objects in the night sky. Similarly, in hunting, a higher twilight factor can make it easier to spot game in the early morning or late evening when light levels are lower.
It is important to note, however, that the twilight factor is not the only factor that affects image brightness and detail in low-light conditions. The quality of the optics, coatings, and other features of the binoculars can also play a significant role.
Exit Pupil & Image Brightness
Did you know that the size of the circle of light that is visible in the eyepiece of a pair of binoculars is known as the exit pupil?
This measurement is calculated by dividing the diameter of the objective lens by the magnification power, resulting in the diameter of the exit pupil.
When comparing the 10×50 and 16×50 binoculars, the difference in their magnification power means that the size of their exit pupils also differs.
The exit pupil of the 10×50 binoculars is approximately 5mm, while the exit pupil of the 16×50 binoculars is approximately 3.125mm.
Why does exit pupil size matter?
Well, it directly affects the amount of light that enters the eye, which in turn affects image brightness and detail.
A larger exit pupil allows more light to enter the eye, resulting in a brighter image with more detail. On the other hand, a smaller exit pupil allows less light to enter the eye, resulting in a dimmer image with less detail.
In addition, individuals with larger pupils may benefit from larger exit pupils as they can take full advantage of the light gathered by the binoculars. Conversely, individuals with smaller pupils may not be able to take full advantage of larger exit pupils.
if you plan on using your binoculars for birdwatching in the daytime, a smaller exit pupil may be sufficient. But if you plan on using your binoculars for stargazing or hunting in low-light conditions, a larger exit pupil may be necessary for optimal image quality.
Field Of View
The field of view is a term used to describe the area that can be seen through a pair of binoculars.
It is measured in degrees and refers to the width of the image that is visible through the binoculars. The field of view can also be expressed as the width of the image at a specified distance, such as 1,000 yards.
When comparing the 10×50 and 16×50 binoculars, the field of view can vary based on the magnification power and the design of the optics.
Generally, higher magnification binoculars have a narrower field of view than lower magnification binoculars.
The field of view can greatly impact the viewing experience and the ability to track moving objects. A wider field of view allows for a larger area to be seen, making it easier to spot and follow objects in motion. This can be particularly important for activities such as birdwatching, where quick movements and rapid flight patterns can be difficult to track with a narrow field of view.
The importance of field of view can also vary depending on the intended use of the binoculars. For example, a wider field of view can be beneficial for sport events, allowing viewers to see more of the action on the field or court.
In contrast, a narrower field of view may be more suitable for astronomy, where pinpoint accuracy and detail are more important than a wider view.
Additionally, the field of view can also impact the user’s perception of depth and distance.
A wider field of view can create a sense of immersion, making the viewer feel like they are part of the scene they are observing.
This can be particularly important for nature observation, where a wide field of view can help the user feel more connected to the environment around them.
If the binoculars will primarily be used for birdwatching or other activities that involve tracking moving objects, a wider field of view may be preferred.
However, if the binoculars will be used for astronomy or other activities that require more precision, a narrower field of view may be more suitable.

Eye Relief
Eye relief is a term used to describe the distance between the eyepiece of a pair of binoculars and the eye of the viewer.
It is measured in millimeters and refers to the distance at which the viewer can still see the entire field of view without any vignetting or distortion.
A longer eye relief allows for more comfortable viewing and is particularly important for people who wear glasses.
When comparing the 10×50 and 16×50 binoculars, the eye relief can vary based on the design of the optics.
Eye relief can greatly impact the viewing experience for people who wear glasses. For those who wear glasses, a longer eye relief is essential to allow them to see the entire field of view without having to remove their glasses. When using binoculars with a shorter eye relief, people who wear glasses may experience a reduced field of view, distortion or vignetting around the edges of the image.
The importance of eye relief can also vary depending on the intended use of the binoculars. For activities such as hunting or birdwatching, where extended periods of use are common, a longer eye relief can be more comfortable and less fatiguing for the eyes. Additionally, hunters may need to wear eyeglasses to correct their vision, and a longer eye relief can accommodate this while still allowing them to maintain a clear view of their target.

Size & Weight
When comparing the 10×50 and 16×50 binoculars, there can be some differences in size and weight.
Generally, higher-magnification binoculars tend to be larger and heavier than lower-magnification models.
The size and weight of binoculars can greatly impact their portability and ease of use.
Heavier binoculars can be more difficult to carry for extended periods of time, especially if you are hiking or traveling long distances.
Larger binoculars can also be more cumbersome to maneuver and use, making it important to choose a size that is comfortable for you.
When it comes to specific uses, the size and weight of binoculars can be particularly important.
For activities such as hiking or travel, smaller and lighter binoculars can be more suitable, as they are easier to carry and use on the go.
Additionally, larger binoculars can be more difficult to pack and transport, making them less ideal for these types of activities.
On the other hand, for activities such as birdwatching or hunting, larger binoculars may be more suitable. This is because they can offer greater magnification and a wider field of view, allowing you to see more detail and track moving objects more easily.
However, it is still important to choose a size and weight that you are comfortable with, as you may be carrying the binoculars for extended periods.
