The Maven B1 10×42 binoculars are loaded with premium optics and materials. Offering a wide field of view and durability, they will work in most settings.
Some of the Best Binoculars Around: A Maven B1 10×42 Review
Hunting, birdwatching, target practicing, traveling to scenic locations, spying on the neighbors (okay, maybe not that one!) all share one thing in common – they benefit from the use of the best binoculars. And it may surprise many to discover that (according to one report) binoculars are “the world’s most used optical instrument, other than eyeglasses.” And binoculars have a diversity of uses, with most being designed for specific purposes. That can make finding the best all-around binoculars a real challenge. Fortunately, there are options like the Maven B1 10×42 binoculars that are ideal for general use to intense birdwatching, hunting, and more.
The Basics on Binoculars
Before we can delve too deeply into the many benefits enjoyed by those using the Maven B1 10×42 binoculars, we need to understand the basics of choosing the right pair. Knowing the terminology around the construction of binoculars is particularly useful.
As most will know, binoculars feature two objective lenses fitted to the large end of each barrel. They also have an ocular lens assembly or eyepiece, a prism system, a focus system, and a diopter adjustment. Some have hinges in the center to allow folding for storage, too.
Any set of binoculars will also have a magnification power that will be described in the name of the product. For example, the Maven B1 10×42 has a magnification power of ten times magnification, and 42 mm for the objective lenses. These are the lenses at the far end or those closest to the object you are viewing. The size of the objective lens gives you an idea of the physical size of the binoculars as well as being a fair indicator of the amount of light they will allow in or gather.
Why would that last detail matter? As one expert noted, when “you understand what these numbers mean and how they affect your viewing, you’ll know if you’re choosing binoculars that will be good for birding, stargazing or using on a moving boat, for example.”
Those figures might also be a good indicator of the likely pricing on a pair of binoculars since the better the optics, the higher the price. The numbers don’t automatically mean a higher cost, though, so don’t ignore a pair because you fear they may be expensive.
Regardless of the size of the lens diameter and the magnification capabilities, binoculars can be found in different sizing. The most common sizing includes compact, mid-size, and full-size. The most compact models have lens diameters less than 30mm (in general), the mid-size include the lenses up to 40mm, while the full-size have lens diameters of 40 or more.
However, and as we’ll see, the Maven B1 10×42 offers the superior size in a smaller, more compact body. This means you can count on a lighter, overall weight that will be easier to carry than many other options with similar configuration.
Some Words on Field of View
It is easy enough to understand what is meant by magnification. Eight times (8x), for instance, brings you eight times closer. Ten times (10x) zooms you in ten times the distance. Zoom binoculars have a lousy reputation because they may have poorer image quality or a bit of shake because it is so difficult to hold them steady enough at high zoom.
As one expert said, “it might seem that more magnification is always better, that’s not always the case. Because magnification also amplifies the movement of your hands, binoculars with magnification powers greater than 10 make steady viewing difficult.”
Then, there is the issue of field of view. Magnification has a direct impact on the field of view because higher magnification automatically narrows the field, while lower magnification allows it to remain quite expansive. It helps to think of it in terms of a wedge that fans out from the end of the binoculars.
When using lower magnification, it allows the lenses to capture that wider field of view, but zoom in to a higher magnification, and that automatically narrows the field of view by enlarging or zooming in on the object. This can make it tough to locate moving objects at a distance. It also decreases the among of light allowed into the lens.
Does this field of view specification matter more than others? No, but it is one of the chief concerns based on your intended use of your binoculars. After all, if you know that you can see something akin to one thousand yards away from where you are standing, and with clarity and sharpness, it is very useful. That is what the field of view specifications provide.
The Objective Lens Diameter
We know that the Maven B1 10×42 binoculars have an objective lens diameter of 42mm. We have also learned that this is an important point because, as we learned, the larger the objective lens, the brighter the view and the more light inside.
When we talk about brighter images, we are also looking at the exit pupil. This, too, is often better if the number is higher. Why? It offers better images in even lower light conditions. The larger the exit pupil, the easier it is for you to also enjoy a good look even if your hand is unsteady.
You calculate the size yourself by dividing the objective lens diameter by the magnification level. So, the Maven B1 10×42 would see you divide 42 by 10 to get 4.2mm as an exit pupil or the size of the shaft of light to reach your eye.
Is this also the same as eye relief? No. Quite plainly, the eye relief of any optic is the amount of space between an eyepiece and the eye, but only when the entire field of view is seen. Those who wear glasses need eye relief of at least 11mm or more.
When choosing binoculars, you will want eyepieces that enable adjustments to each eye to allow optimal eye relief. Often, you can pop down rubber eyecups or turn a collar that shortens the eyepiece.
The best modern binoculars utilize what is known as a roof prism. This means, simply, that the objective lenses and the two eyepieces are aligned. This does not do a lot for improving the performance of the binoculars, but can help them to be manufactured with much lighter weights and smaller proportions. This is something that is one of the benefits of the Maven B1 10×42.
Your Intended Use
Buying binoculars should also be based on more than their magnification power. For example, you most definitely want them to be waterproof as well as fog proof to ensure that you can always use them effectively. They should be designed for comfort, as well. However, that can also depend on your intended use. For example, binoculars with a rubber coating are, generally, appealing. However, when they are also designed to be highly portable and lightweight, it may be more important if you are doing a lot of birdwatching or using the binoculars in a field pack.
Recommended magnification levels are available for most of the common uses of binoculars. For example, hikers and backpackers require a good set of lightweight and durable binoculars for navigation and sightseeing. The rubber coating is ideal for such uses, and yet they should also be compact and easy to lug around on the trails. So, an 8x to 10x magnification is often ideal, and a lens diameter of 28 to 25 is usually a good fit.
What are other “common” sizes recommended? Below are the typical magnification and objective lens combinations listed with their standard uses:
Birdwatching – 8×32 or 8×42 are common. A 10x magnification may be great for smaller birds, but with an 8x magnification, the trade-off is a wider field of view. They should be waterproof and fog-resistant, too.
Boating – Canoeing or using a powerboat, going whale watching, or being on the open water calls for lower magnification that supports steadier viewing. So, an 8×32 pair is a very common choice.
General outdoor viewing – Whether you are on a safari, going out into the yard to watch the squirrels, or looking for excellent binoculars for use on the waters, a 10×42 is likely to be the best. The 10x is going to bring even a rather distant creature into clear view.
Stargazing and sky watching – When you want the best experience beneath the stars and skies, it is all about magnification, and that’s the time for something like the Maven B1 10×42 that offers the high magnification with the larger lens diameter.
Hunting – Many experts say that a 7x to 10x magnification is ideal and that long-range shooting benefits from up to 16x (though a rifle scope may work far better). The larger the lens diameter, however, the shakier the view, and so a tripod might be necessary if using more than a 10×42.
Concerts – If you buy in the famous “nosebleed” section or you are at a festival where getting close to the stage isn’t possible, you want an 8x or more, and the 25 to 30 lens diameters work well.
And just how will the Maven B1 10×42 measure up to these demands? Let’s take a look to find out.
An In-Depth Look at the Maven B1 10×42 Binoculars
Now that you have a good idea of the basic criteria to use when choosing the right binoculars, it is going to be easy to see how superior a set like the Maven B1 10×42 binoculars will be.
They have, as you know, a 10x magnification and an objective lens diameter of 42mm. They have the ideal amount of eye relief for all users (those with or without glasses) as it is a very generous 16mm. They also provide an extremely wide field of view of 341 feet at 100 yards, and this still allows almost 91% light transmission.
The focus knob on the Maven B1 10×42 binoculars is knurled aluminum and requires only a tiny amount of pressure to use and which promises smooth adjustments. The single hinge also features a threaded socket for tripods.
Weighing only 29.75 ounces makes them very packable, and they are compact measuring only 5″ x6.2″ x2.1″ – which is an ideal size for packing or carrying while birdwatching. With a rugged magnesium frame and roof prism, they are reliable performers.
The glass is made with extra-low dispersion elements (also known as ED glass), which reduce any color fringing and blur. The prism has dielectric coatings that guaranteed the optimal levels of light reflection from that roof prism. The barrels are nitrogen purged, meaning that they have no risks for fogging, and will endure even the coldest conditions.
The objective lenses are also deeply set inside the threaded barrels, meaning you can use 49mm filters of different kinds, among other accessories. The eyepieces are also generously spaced at 55-74mm, ideal for all adults and many children.
Though you can see that the Maven B1 10×42 binoculars are ideally suited to many purposes, they have been repeatedly recognized by several photographic and bird enthusiast groups. For example, the Maven B1 10×42 binoculars were the winner of a National Geographic award in 2014 for their clarity and depth of field. The Audobon organization also recognized the Maven B1 10×42 binoculars two years later for their brightness and their premium optics.
They use feature high-quality aluminum adjustments for field performance and durability, and as if all of that were not enough, the Maven B1 10×42 binoculars also feature a lifetime warranty (which is also transferable).
If you are looking for a compact to mid-sized binocular for a wide range of uses, the Maven B1 10×42 is recognized as one of the most affordable and premium options. With a magnesium frame (rather than a standard plastic frame), they are heavier, but much more rugged. They support ED glass elements that enhance their performance, and the lenses are also hydrophobic, meaning they won’t scratch easily or be harmed by oil or water.
They are superior low-light performers that can add a lot of time to your viewing capabilities. The Maven B1 10×42 may have a higher price point for the average mid-sized binocular, but most owners are delighted by their investment and are happy to sing the praises of their Maven B1 10×42 binoculars.
