Features of Vortex Diamondback HD 8x42 Binoculars

Boasting up to eight times of magnification, the Vortex 8×42 Diamondback binoculars are a surefire choice for the best performance. It’s made for the outdoors, optimized with special glass that gives off an unbeatable resolution. Aside from that, this pair of binoculars is a champ on color fidelity, light transmission, sharpness, and accuracy. Over the past years, Vortex has been giving us the best selections of binoculars for all purposes. And with the Diamondback, we have yet another option with a decent price point. Unlike other Vortex binoculars, the Diamond bears ‘HD’ on its name. With this, it’s easy to expect that you’ll get better clarity you simply don’t see on other pairs.

Resolution and Magnification

The Vortex Diamondback can zoom in 8 times using its 42-millimeter objective lens. Although you can get a pair that can magnify 10 times, an 8-time magnifier offers better stability. The Vortex is less shaky than other models. Unless you are bird watching or hunting on longer and greater distances, an 8x binocular will be more than enough. The select glass elements of the Vortex Diamondback give an exceptional resolution. This is paired with cut chromatic aberration that allows you to see colors better. Aside from that, this has a dielectric coating that increases the light transmission on the lenses. Also, there’s an added anti-reflective coating on its air-to-glass surfaces. This provides better clarity, light transmission, and color-accurate images. To top all these amazing features, there’s the Armortek coating that keeps the lenses safe from dirt, oil, and scratches.

Focus Range and FOV

The Diamondback has 320 feet field of view to brag about at a distance of 1,000 yards. This is much better than most binoculars you can see in the market for the same price point. This is a huge FOV that allows you to scan comfortably. Are you an eyeglass wearer? If so, the Diamondback is a great choice. This pair comes with 17-millimeter eye relief. You can keep glassing comfortably, something you wouldn’t achieve on 10×42 binoculars. The Diamondback also has adjustable eyecups so you can use it with or without eyeglasses. Most importantly, it comes with a diopter at the right eyepiece to suit your vision. In terms of focus range, the Diamondback 8×42 offers an excellent 4.5 feet. How does that translate? If a fly lands on your shoes, you can easily focus on it quickly. Again, it’s one of the best in the market. Even the 8×28 that Vortex offers can’t match this.

Optical Quality

If you’re tired of dull binoculars that make it hard to glass on cloudy days, it might be time to switch to the Diamondback. As an 8×42 pair, it offers brighter images. Take note that 10x42s compromises the lighting to achieve better magnification. The prisms of the Vortex Diamondback are equipped with multiple coatings for optimal light reflectivity. Even at dusk, you can see the details clearly and with less effort. However, you should take note that the Diamondback isn’t compatible with the Extra-low Dispersion (ED) glass.


Nevertheless, there’s very minimal color washing if used generally. Although this pair has chromatic aberration, users don’t have to worry about distraction. It doesn’t get in the way, and you can use the binoculars just the same. Moreover, you’ll also get a fog-proof performance with Diamondback, thanks to its O-ring seals and Argon purging. It includes a Pak harness for added convenience. Overall, you can expect crisp and clear images with the Diamondback.

The Diamondback weighs 21.8 ounces with a height of 5.7 inches and a width of 5.1 inches. This feels light with the right feel on your hands. It’s easy to carry around, and you can glass without feeling too much strain on your arms and hands.

Adjustment Ease

The Diamondback is easy to adjust, but there are also some issues. The eyecup and focus knob work smoothly. The eyecup even has hard stops to hold your preferred setting in place. Take note that the Diamondback only has three hard stops, which is one notch shy of its competitors that have four. Nevertheless, it’s just a small issue that can forgive, given the excellent clarity and color-correctness of this pair. Also, you have to be careful with the diopter as it tends to be a little stiff. Aside from that, the main hinge is a little difficult to adjust since it’s much stiffer than other models. If you’re using the binoculars repeatedly, then this stiffness is right for you. It can be a little draggy, though.

Overall Appearance and Construction

The best thing about Vortex is it creates excellent binoculars for a very decent price. Construction-wise, the Diamondback stands out from the competition. It offers the best value for money above any binoculars you can find in the market. The Diamondback has rubber armor with a non-slip grip as well as durable external protection. And for those using a tripod, this bin is highly adaptable. In fact, you can also mount this on your car window if need be. Overall, the Diamondback is very grippy, with the thumbs nicely resting on the ribbed area. Also, it has an O-ring sealed body so you can use it on wet conditions. In fact, this has been tested for Alaskan weather, which guarantees that it will endure the harshest condition.

Disadvantages of Vortex Diamondback HD 8x42 Binoculars

Like any other things, the Vortex Diamond has its own downsides. For those who are looking for the ultimate zooming power, the Diamondback is two notches short of the maximum available power available in the market. Also, if you are to use its tripod socket, you need to secure a Vortex uni-adaptor. You have to purchase this separately. These two disadvantages are just small issues if we are to compare it to the features of the Diamondback. For its price, this is already a steal. Every hunter and bird watcher should consider this for their next outing.


We hope this Vortex Diamondback 8×42 review helped you decide if this pair is the right choice for your activities.
