So, a 10X or a 12X binocular would be ideal, right? Unfortunately, not. You see, there is a big trade off, because the higher the magnification your binoculars have, the more you lose things that are essential to bird watching. For example, the higher the magnification the shakier the image will be.
The 12X50 binocular “size” is like the prom king of bino configurations. It's ideal for stargazing, long-range shooting, and spotting the prey at a distance. The best 12X50 binoculars are durable, waterproof, and come at a reasonable price.
Many binocular manufacturers have settled on 8x as the standard for general birding. This gives you a good field of view with sufficient magnification power for all birding use cases, and, in general, the 8x binoculars are easy to hold steady.”
At such a long distance, the difference is not great. But when you start getting in close, FOV becomes an important factor. So, when you require more FOV, go with a 10x binocular. If you need distance, then the 12x binocular is for you.
The consensus is that 8X42 is the best all-around birding binocular “size.” Additionally, birding binoculars should be durable, provide crystal clear views, and not break the bank.
There's quite the lean towards having an 8X42 binocular for birding. For many birders, it just makes sense. The wider field of view and larger exit pupil makes for spotting fast-flying and camouflaged birds much easier than when using a 10X42.
Just like how larger windows in your house let in more light, the larger surface area of 50mm lenses ensures that they “capture” more light than 42mm ones. More light means more information and thus, a brighter and better quality image would be produced through 10x50 and 12x50 binoculars than 10x42 binoculars.
12 power binoculars are still light enough for hand holding and they don't have that much narrower of a field-of-view (FOV), which could cause you to be extra shaky.
Three of many possible binocular sizes: 15x56, 12x50 and 7x42. These three pairs all work well for astronomy.
The universal consensus is that the 10x has to be better because of its higher magnification. Many hunters, shooters, and birdwatchers argue that being able to bring an object 10 times closer versus 8 times closer is the most important aspect of a binocular.
To determine the size, divide the objective lens diameter by the power. For example, an 8x32 model has an exit pupil of 4mm (32÷8=4). Exit pupil is a very rough guide to image brightness. Binoculars with large exit pupils provide brighter images under very low light conditions.
The binoculars are perfect for outdoor activities such as hunting, bird watching, astronomy, camping and much more. They are powerful to observe every detail of your objective and have a large 50mm lens to capture all the transmitted light. 342ft/1,000Yds Large field of view.
* [12X50 HD high-power monoculars] Provides 12 times magnification, the objective lens is up to 50 mm in diameter, and the best viewing distance is 96m/1000m, providing clear and bright images and different views. It is very suitable for bird watching, hunting, hiking, camping, traveling, wildlife, scenery, etc.
The magnification power of a 12x50 is 12 times magnification (12 times larger than normal unaided vision). So the "zoom difference" would be an increase of 20% in the magnification from a 10x42 to a 12x50. The objective lens diameter determines light gathering capability and the size of the field of view.
Your eye can see a ship sail over the horizon at around 12 miles. So, your binoculars can also see 12 miles and will see the ship 10x larger, but that might not help you discern very much. Think about it this way, if the ship was 10 miles away, a 10x magnification would make it appear 1 mile away.
Generally, binoculars with a magnification of 6 to 10x are easier to use, but for birdwatching, tracking moving objects, and keeping shaking to a minimum, 8 to 10x magnification is best. For theatergoing, a somewhat lower magnification is easier to use, and portability is an important factor.
Model numbers on binoculars essentially tell you their strength (magnification power) and size (objective lens diameter). In 8x42 binoculars, for example, “8” is the magnification power and “42” is the diameter (in millimeters) of the objective lenses (the lenses closest to the object you're viewing).
【Powerful 12x42 Binoculars, but Lightweight Enough, only 1.1 pounds】 Adorrgon 12x42mm binoculars deliver 367ft/1000yds large field of view. Capable of delivering a clear face from more than 650 feet away. Perfect for bird watching, hunting, sports events.
Bottom Line: The Vortex Diamondback 10X50 has less brightness loss than the 10X42, but it comes at a cost of more weight and smaller field of view. The lack of focus around the 10X50 edges is slightly better.
An 8x or 10x, no larger, would do great for the hunter looking to call something into spitting distance, but still give their vision the edge that binoculars do. And often times for archery elk, you may do a combination of spot and stalk and calling tactics, so having an optic that is suited for both is ideal.
More light means more information and thus if all else is equal, there is the potential for brighter, better quality views through 10x50 binoculars versus 10x42 binoculars. However just being able to capture more light does not automatically make for a brighter, better quality view.
At 7x magnification, you won't get quite as close to your feathered friends as with most other binoculars. On the other hand, the field of view (FOV), which ranges from over 400 feet to about 500 feet is great for finding them in the first place.
So, you gain a lot of field of view with 8x42. The exit pupil is approximately 10% bigger on 10x50 than on 8x42, which will still have a small edge in low-light performance. In terms of comfort, 8x42 is better regarding the size and weight – on average, there is about 200 g of difference.
A: The number before the X is the power or zoom of the lens and lets you know how much they will magnify an object. An object in 10x50 binoculars will be 10x closer than the naked eye. The second number is written in millimeters and represents the diameter of the lens.
