Vortex Diamondback 10×42 Binoculars Review

Last Updated: 29.11.21

Main advantage

Optics performance matters most, no matter what binoculars you want to purchase, which is why the Vortex Diamondback 10×42 delivers as not many other similar products can. First of all, because it comes equipped with a roof prism design, it ensures that the quality of the image you see through its lenses is outstanding.

The optics on this model are fully multi-coated, which allows excellent light transmission, which, in turn, makes the image brighter for you. Also, if you compare this model to others, you will notice that the amount of detail you can observe through the lenses is higher. In other words, the HD letters added to the name of this model are there for a reason, and better resolution is that reason.

More than the enhanced light transmission, the Bak-4 prisms coated with a phase correction layer ensure that you get better contrast on these binoculars. Even in low light conditions, this model performs well, which is why it can be the perfect travel companion for you.

The quality of the optics employed on these binoculars justifies their popularity. The model is superior to many others on the market, including binoculars made by the same company that also enjoy an excellent reputation.


Main disadvantage

Although there is a possibility to attach the binoculars to a tripod, doing so might prove trickier than expected. The reason why it is so lies with the fact that these binoculars also require the special Vortex adaptor so that you can use them with a tripod.

Therefore, you will have two extra expenses to make, not just one, so you will have to make sure that you budget carefully for them. Seeing how the binoculars are not exactly lightweight, holding them for a long time can prove strenuous. Therefore, you will need a tripod and an adaptor, too.

Main features explained


Comfort of use

Details matter or manufacturers from all industries wouldn’t strive so much to gain new customers or convince their old ones to switch to a new product. As someone who might have used binoculars made by this company in the past, you might wonder how this model is better than others that are preceding it. The answer lies in the details that make these binoculars more comfortable to use than many other models.

For instance, the focus knob is smooth to operate. Too many times, people get disappointed in binoculars that otherwise offer excellent optics performance, but neglect to provide the user with some features that would make operating them a smooth and enjoyable process. On this model, you will be pleasantly surprised to see that the focus knob turns quickly, and the resistance you’ll meet will be consistent all the way.

Another thing that was improved for this model is the central hinge. As you move the barrels as you see fit, you will notice that the resistance is adequate and that you can easily adjust the binoculars to get the most out of them. Other aspects, such as the eyecups, might not have gone through the same process of enhancement, but they are still great, and overall, these binoculars offer you an outstanding experience.

The adjustable eyepieces contribute to the overall comfort you will experience while using them. Another thing that needs to be mentioned here is the 16-mm eye relief. That means that you will be able to use these binoculars with your prescription glasses on, which, for many users, it’s a great thing.

The clear markings on the eyecups make everything easy, and you will also notice a locking diopter on the right eyecup that allows you to move them up and down.

A construction that will support a lot of wear and tear

You will surely want your binoculars to last for a long time, seeing how comfortable they are to use and the superior optics performance they provide. That is why you will surely be glad to discover that this model is built to withstand a lot of wear and tear without a hiccup. First of all, the material used for their body is high-strength polycarbonate. Besides being sturdy, they are also lightweight, and all due to the material used.

There are several advantages provided by polycarbonate, besides overall sturdiness and reduced weight of the unit. Polycarbonate is resistant to shocks, and it is shatter resistant. Whenever you drop the binoculars by accident, they will most likely resist, and you won’t have to replace them. Of course, it is not only because of the polycarbonate body that you can enjoy such a great pair of binoculars.

The manufacturer thought about employing a rubber armor on the outside of this unit, and that makes the optics inside even better protected from shocks, falls, and other unfortunate events. Another benefit of the rubber coating comes into play; when you hold the binoculars, you will feel the comfortable grip that also doesn’t let them slip from your hands even in wet environments.

That brings us to something else that must be noted about this model. Be it snow or rain, the binoculars will behave admirably, as they are waterproof and fog proof. Although bird watchers are particularly enthralled with this model, you will find that many other users love it.

Whether you want to take it with you on a maritime trip or when hunting, you will find them handy and adequate for any weather. Also, the argon purged construction ensures that no water vapors will fog the lenses inside your binoculars.


Superior field of view and close focus

While the optics performance on these binoculars is excellent in every way, you might be interested in a few features that make them even more suitable for bird watching and other outdoor activities. One of the things that makes this model from Vortex stand out from the crowd is its exceptional field of vision. As you may well know, the field of view you can observe through a pair of binoculars depends on the magnification and lens size.

In this case, the 10×42 configuration is ideal for guaranteeing a simply optimal field of view. If you go for a model with larger lenses, you will notice a drop in the achievable field of view. Should you prefer a model with smaller lenses than 42mm, as they are on the model we’re talking about here, you will notice that the field of view is better, but you can’t benefit from the same outstanding light-gathering abilities.

For this model, the field of vision is 345 feet at 1000 yards, which is ideal and right in the ballpark with other praised binoculars. To get an idea about how it compares to others in its series, the 50mm model has a field of view of only 283 feet at 1000 yards, while the 32mm model delivers 341 feet at 1000 yards, as far as the field of vision is concerned.

That’s pretty important for bird watchers who want to observe the landscape around them so that they can catch through their lenses some elusive species. Another essential thing for them is having a superior close focus. At 5 feet, this model delivers excellent close focus, which explains why so many bird watchers are in love with it, and not only. Observe birds from a distance, or bring them into focus, and you will know why this model is so praised.


The HD option offers so much more to bird watchers

The Vortex Diamondback 10×42 is an HD model, and you may wonder what that is all about. Hunters, bird watchers, and other people who observe their surroundings when taking trips to the great outdoors need their binoculars to deliver the image quality and brightness that allows them to notice the minutest details. A single look through the lenses of these binoculars will convince you that the picture-perfect quality they deliver is everything you need.

It should be said that the lenses on this model are made with premium glass that manages to reduce chromatic aberration, which is a common plight for many such units. At the same time, one cannot help but notice that this model from Vortex is still reasonably priced, seeing the performance delivered. In other words, if you want to go bird watching or hunting, and enjoy perfect image quality, you should get these binoculars even if you must shop on a budget.

Compared to non-HD models, this pair of binoculars delivers superior results in every way. First of all, the image you will see through these binoculars is much sharper, and you will enjoy excellent contrast and brightness. The overall resolution is much better, as well. That is why it would be perfectly justifiable to get an HD version of a pair of binoculars, as the advantages are numerous and evident.

Due to their sturdy construction and superior optical performance, these binoculars truly stand head and shoulders above the competition. Seeing how the HD resolution also brings many benefits to bird watchers and not only, they deserve the high praise they have received so far. Take full advantage of the enhanced optics when you go bird watching, hunting, or hiking. Even whale watchers and other people who enjoy maritime adventures will love them.
