In essence, they decode the magnification power and the diameter of the objective lens, offering you a window into a realm of enhanced vision. Let’s demystify what does 30 x 60 mean on binoculars together.

Key Highlights

  • The numbers 30 x 60 indicate 30x magnification and 60mm objective lens diameter, influencing clarity and brightness.
  • The 30x magnification allows for distant observations, making these binoculars suitable for long-range viewing.
  • With a 60mm objective lens, these binoculars balance portability and light-gathering ability for various outdoor activities.
  • The specifications imply versatility, suitable for activities like bird watching, sports events, or general outdoor use.

What Does 30×60 Mean on Binoculars?

The first number you see on the binoculars is the magnification, while the second represents the effective objective lens diameter. So 30, in the case of 30×60, represents the magnification which is the number of times the optical gadget enlarges your desired sight of view.

Effective lens diameter or objective lens diameter is the second number written on the binoculars, like 60 in the case of 30×60 binoculars. Now, if you are wondering what the magnification and effective objective lens diameter are, don’t worry, as we will have a detailed discussion about them.

Understanding What Does 30 x 60 Mean on Binoculars


The magnification of the binoculars is the degree to which a pair of binoculars brings the world closer to your eyes, which means that while using 30×60 binoculars, you will be able to see the view 30 times magnified as compared to the one seen by the unaided eye.

But one thing to keep in mind is that the higher the magnification is, the narrower the field of view is. Thus with an optical gadget providing a massive magnification, there are chances that you would miss the bigger picture of the view; therefore, the rule of “the bigger, the better” doesn’t work in the case of magnification.

Another vital thing to consider is that using a pair of binoculars providing a magnification of 30x often comes with the problem of the image’s shakiness. The use of a tripod is recommended to resolve this issue.

Most specialists agree that the optimum magnification for a pair of binoculars lies somewhere between 7x and 10x, depending on the purpose for which you want to use particular binoculars. For instance, you need a magnification of 10x or higher for astronomy binoculars.

Objective Lens Diameter

Objective lens diameter shows the size of the aperture, which controls the amount of light transmitted; thus, a hefty objective lens like 60 mm displays excellent light-gathering ability. Hence, the larger the lens diameter, the more light it transmits and the brighter the view you would get. 

Moreover, the size of the objective lens also directly impacts color reproduction. Let’s be honest; everyone wants a pair of binoculars that provide bright and sharp imaging from dusk to dawn. It will help if you consider the option that offers you a large, at least 50 mm or more objective lens diameter that can ensure a quality view with true-to-life color from sunrise to sundown.

An important thing to consider is that the objective lens’s size directly impacts the binoculars’ size and weight. Therefore a pair of binoculars with a large objective lens like 60 mm weighs more than its counterparts.

Exit Pupil

Lastly, there is something that is not written on the body of the binoculars, but it indeed makes a lot of difference in the viewing experience that your binoculars offer. This factor is none other than the exit pupil. The exit pupil is the breadth of the stream of light leaving the eyepiece of the binoculars.

It is a virtual aperture in an optical gadget and a small bright circle that can be seen in the eyepiece’s middle. The exit pupil number is something you should also consider because it tells how much brighter your image would seem to be in low-light conditions. The higher the exit pupil number is, the brighter the image you will get. 

It is calculated by dividing the objective lens’s diameter by the magnification it provides and is usually expressed in millimeters. Now, in the case of 30×60 binoculars, the exit pupil will be 60/30 = 2 mm. Now, this 2 mm exit pupil is quite average, and there is no doubt that it does an excellent job in daylight, but when it comes to nighttime, there are better choices than 30×60 binoculars.

The best low light binoculars offer an exit pupil of 5 mm or higher. For daytime view, an exit pupil of 5 mm (or in some cases even smaller but higher than 2 mm) would serve right as the exterior light is enough. At night an exit pupil of 7mm is usually recommended to get a clear and crisp view.

How to Choose The Best 30×60 Binoculars?

Binoculars are an excellent tool for the outdoors. They are handy for bird watchers, photographers, and sportspeople. But the binoculars are so much more than that. They are also a great way to see the world from different perspectives.

The best binoculars will have various features like excellent picture quality, crystal-clear images, and optically stabilized systems. These features make the picture clearer. If we are looking for distant views, these types of binoculars are what we need to have as they provide clear pictures. Moreover, the best ones will be chosen from various brands, so you can buy something that fits your needs and budget.

So following are some of the features that you should consider while buying 30×60 binoculars.

Field of View

The field of view accounts for the total area or the horizontal width of the view you can grasp with a pair of binoculars without moving your head. In the case of the field of view, the wider, the better rule sets in as with a wider field of view, you would be able to spot the thing you want to focus on instantly, and it would ensure that you won’t miss out on any crucial or once in a lifetime moment.

A field of view wider than 315 feet at 1000 yards (105m at 1,000 meters / 6.0°) would serve its purpose justly.

Lens Coating

The binocular lens coatings mostly add to the light transmitted through the lens. Hence increases the brightness, saturation, and contrast of images with better color reproduction and color fidelity, where contrast means the difference in luminance between adjacent bright and murky areas.

The higher the contrast is, the sharper and more brilliant the imaging is perceived to be. You should look for fully multi-coated lenses as they have several coatings on all air-to-glass surfaces with different refractive indices. The fully multi-coated optics being on the high-end ensures the amount of reflected light to its lowest.

At the same time, it considerably increases the optical performance and ensures impressive low-light performance. Last but not least, the fully multi-coated lens also guarantees the absence of any chromatic aberration.

Eye Relief

So no doubt that with a high magnification like 30x, you have to make a compromise in the eye relief, but that does not mean that it should be wholly forgotten. Eye relief is the optimum distance between your eyes and the eyepiece of the binoculars.

More precisely, it is the distance from the eyepiece lens’s outer surface to the point where the exit pupil is formed. The viewer can only grasp the whole essence of the picture if his eye is within this distance.

Prism Type

Prism serves to invert the otherwise upside-down images so that you can see the view as it is. The binoculars come equipped with either a Porro prism or a Roof prism.

A Roof prism is lighter in weight, smaller in size, with more optical precision, and a bit more expensive than the bulky Porro prism, which, on the other hand, offers greater depth perception. 

Durability and Weather Resistance

Durability is a feature you should pay attention to while buying a pair of binoculars. Most binoculars now offer rugged rubber armoring that adds an extra layer of protection for the binoculars and gives them a firm grip. Apart from that, you can only sometimes predict the weather when you are out on the field to watch your favorite sporting event or your favorite artist’s concert.

So you and your optical gadget should always be ready for any erratic change in weather. So you should look at the model’s durability because, frankly speaking, Guys! You are spending your hard-earned money on buying the optical device. Hence your binoculars should provide you with features like waterproofing, fog-resistance, scratch-resistance, dust proofing, etc., so that you won’t have to worry about the view’s haziness in a humid environment or the accidental water splashing on your 30×60 binoculars.

Budget is also an essential factor that drives your binoculars choice. We suggest you go for something other than a cheap option because, in most scenarios, the price of a product reflects the quality and features it offers. Think of it as a long-term investment because you never know by choosing a cheap product.

You might spend more on repairs or replacement than investing in a pair of optically precise and substantially useful quality binoculars.

How to Choose The Best Tripod For 30×60 Binoculars?

The first thing you need to do before buying a binocular tripod is to identify what type of binoculars you want to use, as we are going to use the 30×60 binoculars, so this much is sorted. You can move directly to the second step. 

After identifying the binoculars you want to use, look for a tripod that is compatible with it. Choosing the best binocular tripod for your needs is a challenging task. There are many factors to consider when searching for the right one. Some of these factors include: how much weight they can carry and what kind of terrain you will be hiking or backpacking on to see whether or not the tripod is stable enough for that terrain. You should also consider the tripod’s construction material, aluminum or carbon fiber, etc. The last thing you will need to do before buying a tripod is deciding whether you want an adjustable height or a fixed height and what the tripod head is like.
