Which is Better 10×50 Binoculars vs. 10×42 Binoculars?
The two numbers used in the description of binoculars make some optics more attractive, noteworthy, and useful in certain areas than others. 10×50 and 10×42 binoculars are some of the most popular in the market today. Here is what they mean and why you should consider them when looking for the best binoculars.
The first number stands for the magnification power, while the second one stands for the diameter of the objective lens. 10×50 and 10×42 devices have the same magnification power. When you use them, objects will appear 10 times closer than when viewing with your naked eyes.
The main difference between the two types of optical instruments is the diameter of their objective lenses, which is measured in millimeters. The diameter of the 10×50 optics is 50mm and 42mm for the 10×42 instruments.
Usually, there are multiple different sizes of objective lenses, and this causes confusion among many buyers. The choice of the magnification range when buying binoculars is crucial. What about the size of the objective lens? How does the objective lens affect the performance of the devices? Read on to find out:
The lenses of 10×50 binoculars are bigger than that of 10×42 binoculars by 8mm. You can see the differences by looking at the end of the barrels, where objective lenses are set. Usually, the two versions have similar eyepieces.
Factors to Consider When Choosing the Objective Lens
When shopping for objective lenses, you should keep a few factors in mind. For example, consider the size and weight of your binoculars and the magnification power. Larger objective lenses also have more weight.
Large lenses require large casing in binoculars. Although the manufacturers can use different materials to reduce the weight, the weight will increase with the increase in the size of objective lenses.
Therefore, 10×42 binoculars are bulkier than 10×42 versions. The weight can be a challenge for some binocular users, especially when trekking for long periods. If you prefer high magnification, consider using large objective lenses as they’ll produce clearer images.
However, if you’re viewing targets at close range, optics with larger lenses may be less effective. Another important consideration is lighting. If you intend to use your optical instrument in dark areas, large objective lenses are better as they’ll allow more light to enter.
As a result, you’ll see your targets with ease. However, it’ll not guarantee a wider field of view. For low magnification power, a small objective lens will give good results. The size of the objective lens also influences the physical size of most optical instruments.
If you opt for devices with small objective lenses, colors, and the details of the images will be limited even when in areas with bright light. Large objectives are necessary if you need to get sharp views and good color.
In terms of cost, your decision on whether to go for 10×42 or 10×50 binoculars will be based on how much money you intend to spend versus the benefits and drawbacks of using either of them. Usually, you’ll be required to pay more for 10×42 than 10×50 binoculars.
The cost will vary depending on many factors, including the brand and where in the world you are shopping. Prices for 10×50 binoculars tend to be higher than that of the 10×42 versions by up to 20%.
