10X42 vs 10X50 Binoculars

The comparison between 10X42 and 10X50 binoculars is not an easy task. We tested them extensively to get the best information and know which performs better than others. Keep in mind that our requirements, preferences and choices vary. We hope to give you all the information that will help you make your decision according to your requirements. 

Objective lens:

In binoculars, objective lenses are glass elements present in front of binoculars. This objective lens varies in size and is measured in millimeters. Bigger objective lenses have more ability to capture the light, whereas the smaller objective lens has the little capability of capturing the light.

The manufacturers use a more significant sized objective lens to increase the light capturing ability. When the binoculars capture more light, they give a brighter image and can be used in low light conditions.

The objective lens in 10X50 binoculars is bigger and better than 10X42 binoculars. The difference of 8mm has a significant impact. Due to the ideal size of the objective lens, 10X50 binoculars can be used in low light conditions, especially when clouds are around the corner. 

In 10X42 binoculars, the objective lens is smaller, and that can’t be used in cloudy weather when light is not good. So 10X50 binoculars go a step ahead of 10X42 due to their low light usability.

Weight:

As mentioned above, 10X50 binoculars have a bigger diameter than the objective lens. A bigger objective lens means more glass has been used to build them. The size of barrels also increases. Due to the usage of more glass elements, these binoculars become heavier. 

In 10X42 binoculars, the objective lens is smaller and less glass material is used to make them, so they are comparatively heavier than 10X50 binoculars. So they have the edge over 10X50 due to less weight.

Exit pupil:

Exit pupil is a small aperture on the eyepiece where light rays leave binoculars and enter the eyes. A better exit pupil means a more clear, sharper and brighter image. It is calculated by dividing the diameter of the objective lens by the magnification power. An ideal exit pupil is 5 mm.

In 10X50 binoculars, the size of the exit pupil is 5mm, which is perfect for every age person. Whereas in 10X42 binoculars, the size is about 4.2 mm, which is not bad. But in comparison with 10X50 binoculars, this is far behind. So, 10X50 binoculars give a sharper and better image with solid clarity.

Size:

After reading the objective section, we are confident that you will not require our assistance in understanding size differences reading the objective lens section. If that’s not the case, let’s dig more into the 10X42 vs 10X50 debate and know about size differences.

10X50 binoculars have a long barrel to accommodate the larger objective lens. The counterpart has smaller barrels or tubes due to their small-sized objective lens. The size of the objective lens directly impacts the size of whole binoculars. So 10X50 binoculars have bigger sizes, whereas 10X42 binoculars have smaller sizes and are compact in shape. We recommend choosing compact binoculars as they are easy to carry in the field. So, 10X42 binoculars go one step ahead.

Low light Usability:

The objective lens in binoculars acts like a window of a room. The bigger the window, the more light will come through them and vice versa. The same is the case with the objective lens. The bigger sized objective lens means more and more light will pass through them. Due to more light, the image will look sharper, brighter and more evident in low light conditions.

But the objective lens of 10X42 binoculars is smaller. The passage of light is not as good as in 10X50 binoculars. They can’t be used in low light conditions. So 10X50 binoculars win the race in case of Useability in low light.

Usually, both binoculars fulfill all the basic requirements as they are water/ fog and shockproof. Their bodies consist of rubber armor and hard plastic, making them robust and vigorous. Nitrogen purging and o ring sealing are also stock in both 10X42 and 10X50 binoculars. The overall built quality is optimal, and we didn’t find any flaw in their quality.
