The Vortex Diamondback 10X42 Binoculars Review-Updated 2023

In the ten plus years that I have been a hunter, I have experimented with a vast array of binoculars and other optical instruments. That being said, allow me to introduce you to one of my all-time favorite binoculars, the vortex diamondback 10x42.

Initially, I bought this binocular as a backup. Interestingly, since buying this binocular close to three years ago, I have used it more frequently than I have used my large Celestron 71454 Echelon and for good reasons. So what is it about this vortex diamondback binocular that makes it such a great optical instrument?

Diamondback Now Available in Vortex Diamondback HD Version- 2023 Update

In 2019, Vortex company announced a new, updated Diamondback version. This one has HD in the name. The naming was changed to indicate a better glass quality.

Of course, we pitted the new HD version against the old Diamondbacks. It is interesting to take a look and compare the new HD version to the Diamondback we have known and loved.

The new HD glass  has resulted in signicant reduction in chromatic aberration or colour fringing.

Reduction in color fringing leasd edges having greater clarity without green or purple haze.

With the Diamondback HD, when compared to the older model, the overall definition of the image  have improved. 

It's not something that jumped out at me, but after some careful comparison, the colour and contrast were more punchy, for want of a better word.

Chromatic aberration hasn't been completely eliminated, which we also cant expect in such a price range however, the improvements have been impressive.


Initial impression was great quality, solid built but not too heavy. Tolerances are all tight with little to no play.

Controls are fairly easy to adjust but are tight enough that they will not move on their own.

Glass is clean and easy to see through. Definitely the weak point of the binoculars, I’ve used other scopes that look much better but for the price it is actually very good

The Diamondback HD is Lightweight and has a heavy-duty magnesium chassis.

Yes, The Diamondback HD has a magnesium body with a rubber coating, not polycarbonate.

Focus Knobs

The new diamondback HD also comes with a more refined focusing knobs. Fiddling with the knobs now feels smoother and easier. The central hinge also feels highly finished and well designed than the previous classic diamondbacks.


Surprisingly, the new Diamondback HD costs almost the same as previous vortex diamondback classics.

We consider this a welcome change owing to vast improvements in the glass quality and some excellent ergonomic design changes.

Great Field of View

The Vortex Diamondback comes in three variants, the 10X32, the 10X42 and the 10X50. Personally, I own the 10X42 variant, which is the subject of this vortex diamondback binoculars review.

The reason why I opted for the 10X42 is that it has a better field of view compared to its siblings. If you know anything about binoculars, then you are aware that a binocular’s field of view depends on its magnification and size of the objective lens. The 10X32 variant has a small field of view because of its small 32 mm objective lens.

On the other hand, though the 10X50 has a larger objective lens it maintains the 10X magnification, which is the cause of its small field of view. This is why the 10X50 has a field of view of 283 ft at 1000 yards while the 10X32 has a field of view of 341 ft at 1000 yards. Contrastingly, my trusted 10X42 has a field of view of 345 ft at 1000 yards.

Comfortable Eye Relief

If you are like me who is very cautious about a binocular’s eye relief and comfort, you will love the 16 mm eye relief of the 10X42 Vortex Diamondback binocular. Compared to the 10X50 version, which has an eye relief of 19mm, the 10X42 is perfect for use with or without eyeglasses. To help you set the right distance, the adjustable eye cups on this binocular have clear markings. On the right eyecup is a locking diopter for twisting the eyecups up and down.


In regards to performance, the 10X42 Vortex Diamondback is quite the performer. Similar to its siblings, this Diamondback model features a roof prism design. Moreover, all the optics are fully multicoated for improved light transmission. On the other hand, the Bak-4 prisms feature a phase correction coating that enhances contrast and resolution. Thanks to its impressive light transmission capabilities I can use my 10X42 Bino during the day as well as during the night. Also, with this binocular, I can focus on things as close as 5 ft. The focus knob turns smoothly and is large enough for turning with or without gloves.

Rugged Construction

Vortex manufactures its Diamondback binoculars from a high-strength polycarbonate. The latter material is both shockproof and shatter resistant. For improved protection from bumps, falls and knocks, the polycarbonate body of the Diamondback binoculars coated with a rubber Amor.

The New Diamondback HD has a magnesium body with a rubber coating.
