What Do The Numbers Mean On Binoculars?

You will see that there are numbers on binoculars – something like 8 x 42 for example. These two values each represent a function that refers to the magnification and the size of the objective lens. The first number represents the magnification power, while the second number represents the diameter of the objective lens.

For example, “8×42” means that the binoculars have a magnification of 8 times and an objective lens size of 42 millimeters. The magnification number indicates how much larger an object will appear through the binoculars compared to the naked eye. So, if you look at an object that is 100 yards away through 8x binoculars, it will appear as if it is only 12.5 yards away.

The objective lens size refers to the diameter of the front lens element, which affects the amount of light that can enter the binoculars. A larger objective lens size generally results in a brighter image but also makes the binoculars heavier.

When choosing binoculars, it’s important to consider the right magnification and objective lens size for your intended use. For bird watching and other nature observations, a magnification of 8x to 10x and an objective lens size of 30mm to 42mm are generally considered good options. For more extreme activities such as hunting or long-distance observation, higher magnification and larger objective lens size may be more appropriate.

Factors to consider when choosing lightweight binoculars for bird watching

When choosing lightweight binoculars for bird watching, it is crucial to consider several key factors in order to find the best fit for your needs and preferences.

  1. Magnification: A magnification of 8x to 10x is considered good for bird watching because it provides a good balance between image magnification and stability. At this magnification range, the image is magnified enough to provide a clear and detailed view of the bird, while still allowing the user to keep the binoculars steady and stable without excessive shaking.
  2. Objective lens size: Binoculars with a larger objective lens diameter or larger front lens element generally leads to brighter images, but it also increases the weight of the binoculars.
  3. Weight: Lightweight binoculars are easier to carry around and less fatiguing to hold for extended periods of time.
  4. Durability: The binoculars should be able to withstand the elements and be resistant to damage from impacts or drops.
  5. Image quality: The binoculars should provide clear and bright images with good color representation and contrast.

By considering these factors and trying out different models, you can find the perfect lightweight binoculars for bird watching that meet your specific needs and preferences.

    How To Choose Compact Binoculars For Bird Watching

    A good pair of binoculars can make a significant difference in the quality of your bird watching experience. Here are some tips to help you choose the best compact binoculars for bird watching:

    1. Magnification and Objective Lens Diameter: The first thing to consider is the magnification and objective lens diameter of the binoculars for a good balance between magnification and field of view. For bird watching, a magnification of 8-10 and an objective lens diameter of 30-40 mm is ideal.
    2. Field of view: The field of view (FOV) is an important factor to consider when choosing compact binoculars for bird watching. A wide FOV provides a broader view of the bird’s environment, making it easier to keep track of the bird if it moves. There is a correlation between FOV and magnification, as higher magnification leads to a lower FOV. However, binoculars with a magnification of 8x or 10x have a good balance of FOV and magnification for bird watching.
    3. Image Quality: Look for binoculars with high-quality glass and coatings to get clear and sharp images with high contrast. Binoculars with Extra-Low Dispersion (ED) or High-Density (HD) glass are great choices.
    4. Optical Coatings: Multi-coated lenses will help reduce glare and improve image quality.
    5. Size and Weight: Compact binoculars should be lightweight, easy to carry, and won’t weigh you down on traveling.
    6. Durability: It is important to choose binoculars that are durable and waterproof as Bird watching is mostly an outdoor activity. Look for binoculars with a rubber coating for added protection against the elements.
    7. Focus: A good focusing mechanism with a smooth focus wheel makes it easy to use and enhances the viewing experience without any frustration.
    8. Price: The price of binoculars can vary greatly. It’s important to find a good balance between price and quality. Don’t sacrifice quality for a lower price, but also don’t overspend on features that you don’t need.

    How to Use Binoculars for Birding

    Before you start using the binoculars, you have to adjust them to suit your measurements and preferences. Here’s how you do that.

    1. Start with the Eyecups

    You will see eyecups on almost all binoculars. If you wear glasses, you have to look through them. So keep the eyecups down so that it accommodates your eyewear. And if you don’t wear glasses, then just keep the eyecups up so that they act as a shade for you.

    • Fix the Hinge

    In your binoculars, there are two long eyepieces that are connected to each other by a hinge in the center. You can move this hinge to increase or decrease the distance between these eyepieces. So you gotta do that first.

    Pull the two eyepieces farthest apart, then hold them to your eyes and start to pull them back closer to each other until the two vision circles that you see through the two eyepieces merge into one whole big circle.

    • Get to Focus 

    There is a focus wheel on the top middle part of your binoculars. There’s only one wheel, so you can’t miss it. Hold the bins to your eyes and adjust the wheel to focus on objects that are at different lengths from you.

    You will need to keep a finger on this wheel at all times so that you learn to automatically adjust the focal length with it so that you can keep following birds at different levels very quickly. The better you get at controlling this wheel, the more birds you will be able to spot within a short time frame.

    How to Use Binoculars with Glasses

    If you wear glasses and need to use binoculars, there are a few options to ensure a comfortable and clear viewing experience.

    1. Use Binoculars with a Longer Eye Relief: Binoculars with a longer eye relief will allow you to see the entire field of view even if you’re wearing glasses. Eye relief is the distance between the eyepiece and your eye.
    2. Use Binoculars with Twist-Up Eyecups: Binoculars with twist-up eyecups can be adjusted to accommodate glasses by twisting them up, thus creating a gap between the glasses and the eyepiece. The most comfortable distance for spectacled eyes is 12 mm.
    3. Use Binoculars with Fold-Down Eyecups: Binoculars with fold-down eyecups can be adjusted by folding them down to create a gap between the glasses and the eyepiece.
    4. Invest in Binoculars with Interpupillary Distance Adjustment: This feature allows you to adjust the distance between the eyepieces, which is particularly important if you wear glasses.
    5. Wear Glasses with Thin Frames: Wearing glasses with thin frames can reduce the chances of interference between the eyepieces and the glasses.

    Cleaning Binoculars Internally

    Your binoculars are quite intricate, and they shouldn’t be treated roughly. You need the proper equipment to clean them thoroughly. We’re going to describe the process briefly here.

    Step 1: Air Blasting Time

    Use an air blaster in order to blow air into the lenses, knobs, and all other crevices you can find.

    Step 2: Small Brush Time

    Get a small brush tool with fine and delicate bristles to brush off the dust and debris that still remains in the crevices after you air it out. At this point, give the lenses a thorough brush down so that you don’t miss any spots. Your binos shouldn’t have any dust after this step has been completed.

    Step 3:Time To Gently Scrub It Down

    Now take a lens solution and a microfiber cloth. Then soak up the cloth with the solution and start rubbing the lenses down very gently. Do not use any other means of cleaning your lenses or any other part of your binoculars because that might leave scratches on them. And that’s it; you’re done!

    Roof Prisms vs. Porro Prisms For Birding

    Roof prisms and Porro prisms are two different types of prism systems used in binoculars to reflect and redirect the light to the eyepiece.

    Roof prisms are used in compact and waterproof binoculars and have a straight shape, which makes them more compact. They reflect light straight through the prism and thus have better image quality compared to Porro prisms. Roof prisms also require high precision in manufacturing and are therefore more expensive.

    Porro prisms, on the other hand, have a zigzag shape, which makes them less compact but also less expensive than roof prisms. They reflect light twice, leading to more light loss, but provide a wider field of view and more depth perception than roof prisms.

    FeatureRoof PrismsPorro Prisms
    OpticsAligned in a straight line, resulting in a compact and sleek designBent at a 90-degree angle, providing a wider separation between the lenses
    Image QualityTend to have higher quality images due to the straight-line optical pathCan produce slightly inferior image quality due to the bent optical path
    DurabilityUsually more durable due to the compact design, which minimizes the number of moving partsCan be more delicate and susceptible to damage due to the bent shape
    CostTypically more expensive due to the higher level of precision required in manufacturingOften less expensive, but still provide good quality images
    Size and WeightUsually smaller and lighter due to the compact designUsually larger and heavier due to the bent optical path
    ComfortCan be more comfortable for people with glasses as the eyecups fit more closely to the eyesCan be less comfortable for people with glasses as the eyecups do not fit as closely to the eyes

    In birding, the type of prism system used depends on personal preferences, budget, and the purpose of use. Both roof and Porro prisms can be suitable for bird watching, but roof prisms are favored for their compactness, waterproofing and higher image quality.

    In the end, the perfect lightweight binoculars for bird watching will depend on your personal needs, preferences, and budget. By considering the factors discussed in this article, you can find the binoculars that best meet your needs and help you make the most of your bird-watching experience.
