The Vortex Diamondback 10X42 Binoculars Review

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 binocular that makes it such a great optical instrument?

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.
