  • 18x magnification and 56 mm objective lenses, the Razor UHD binoculars provide ultra high definition optical quality and prescription for unparalleled image resolution, providing exceptional color fidelity, edge-to-edge sharpness, and light transmission.

If you’re a Vortex fan wondering what has this brand brought us with this latest launch, stay with me till the end and let’s take a closer look at this magnificent UHD 18×56 binocular.

Vortex UHD series, the newer, the better!

Vortex always strive to make glassing more comfortable with its new launches; immense popularity of their Razor HD, Viper, and Kaibab series is no hidden secret.

However, to thoroughly facilitate lowlight adventures, the need for an improvised technology was persistent. That’s when the crafters at vortex optics aimed to introduce a newer version of their HD series with exclusive techniques and efficient components.

Vortex UHD series has a unique Abbe-Koenig prism system that impressively enhances light transmission and makes a binocular suitable for every environment.

This prism system has a shallow V-shaped design that bends the light to 180 degrees and stops unnecessary reflection. Eventually, bright imagery reaches the binocular’s ocular lenses with no distortion.

Since Abbe-Koenig prisms are longer than other roof prisms, they improvise color fidelity and decrease light fringing. Vortex UHD 18×56 binocular offers incredibly bright imagery, no matter the light conditions.

This rare prism that makes lowlight glassing brighter is one of the many perks that Vortex has packed in their UHD binoculars. Let’s discuss more features in detail and judge if all this hype is justified or not!

Lens diameter

This Vortex razor UHD binocular has 56mm large index-matched APO lenses that improve color-correction and remove most focal distortions. Vortex has also applied XR anti-reflective coating on these enormous lenses that stops flare, reflection, and chromatic aberration.

When the long Abbe-Koenig prisms are paired with these high-class APO lenses, the optical quality becomes incredible. Regardless of the light present around you, Vortex Razor UHD binoculars will bring forth crystal clear views. Also, unlike other binos with large lenses, Vortex has diligently worked to remove edge-distortion in this bino.

A plasma tech coating is thoroughly applied to these high-density lenses to shelter their surface and provide edge-to-edge clarity.

Field of view

This is a down point of vortex razor UHD 18×56 binocular; you’ll get FOV of 194ft at 1000 yards. This field of view is shorter than other vortex binoculars and might compel you to think that it won’t suit long-ranging missions that much.

However, despite having a concise FOV, this binocular’s power is beyond belief. It lets you magnify, zoom, and focus on an object quickly with remarkable precision. Even if you aim to glance at a vast region, its FOV isn’t a constraint as Vortex has compensated this shortcoming by incorporating other useful features.

Inter-pupillary distance

As vortex UHD 18×56 is a full-sized binocular, reasonable inter-pupillary distance was inevitable in it. We all have different face sizes, and one binocular size cannot suit all. Therefore, this vortex razor UHD 18×56 binocular provides 56-76mm IPD.

Either you need to increase the size or aim to compress the barrels together, altering this bino’s size is easy and secure; you won’t struggle to maintain an IPD. Set once and glass endlessly!

Exit pupil diameter

When the band of light is broad in a binocular, your eyes stay relaxed and receive a vivid picture of the surroundings. However, some old full-sized binoculars lack in offering a good EPD, and glassers often complain of headaches after spending some time in nature.

Vortex has solved this qualm as well; your vortex razor UHD 18×56 binocular has 3.1mm exit pupil diameter. This central aperture won’t strain your eyes; you can stand still and glass through it without tiring your pupils.

Once your Vortex UHD 18×56 binocular is set, you can spend hours observing nature’s beauty through it or trailing your big game; your pupils will stay stress-free, that’s a promise!

Twilight factor

This binocular is the master of low-light glassing. Due to its bright Abbe-Koenig prisms and ED lens glass, it provides matchless light transmission. Similarly, UHD 18×56 binocular’s 31.7 twilight factor increases image brightness when the source of light is unstable.

You’ll painlessly ace your secret vigilance missions or early morning photo shoots with vortex UHD 18×56 binocular. Lowlight used to be a significant limitation for glassers, but not anymore. With a UHD binocular in hand, you’ll rock your lowlight glassing ventures.

Close focus distance

With a Vortex UHD 18×56 binocular, you’ll get a 10ft close focus distance. This CFD helps hunters, birders, and travelers alike by providing them razor-sharp views of nearby objects. 

Also, the large central focusing knob makes zooming on the nearer objects quick and never lets you miss a magnificent sight. Whether you prefer looking at the animals from your camouflaged tree-stand or are a seasoned birdwatcher, this 10ft CFD always comes in handy. 

Eye relief distance

A full-sized binocular with ergonomic features is always hard to find; some tire your eyes while others exert stress on your shoulder muscles. Whichever case of discomfort you face, it affects the charm of glassing.

Fortunately, that’s not a concern with vortex razor UHD binoculars. This massive 18×56 binocular has an 18mm eye relief distance with soft, movable eyecups. When you have set your binocular on a tripod and need some rest, this 18mm ERD works immaculately.

You can step back a bit and still keep your gaze fixed at your favorite spot, thanks to this brilliant eye relief distance. As this binocular has a locking right diopter, you won’t have to re-adjust your focus repetitively. Once nicely set, you can spend a whole day scouting your favorite terrain or glancing at a beautiful tourist destination.


Glassing with a heavy binocular consumes your energy and requires a little practice before you set it right. Some binos have slippery outer body while others cannot be mounted on a tripod adapter. With vortex razor UHD 18×56, however, comfort isn’t a problem.

Despite weighing almost 41oz, this binocular is extremely stable. Its outer chassis is crafted from light-yet-robust magnesium, which shelters the bino’s inner parts. Similarly, secure rubber armor doesn’t let the binocular slip from your grip no matter how harsh the weather is.

This enormous 18×56 binocular has an open-hinge design that unburdens the glassers and allows one-hand holding.

Also, this premium binocular comes with a reliable harness that is easy-to-wear and safe.

As this binocular is massive, one cannot rely on the strap only. This weight will strain your neck, and you’ll need an alternative soon. Keeping your comfort in mind, vortex optics has already added a stylish-yet-secure harness in this package.

A soft neck strap, carry case, and a sleek harness; Vortex Razor UHD 18×56 binocular is decorated with numerous positives.

This bino’s sizeable central focus knob helps the glassers take a closer look at the target, and its right locking diopter saves their favorite site instantly, two positives together. 

Weather resistance

When a binocular performs exceptionally in all kinds of weather and doesn’t require regular maintenance, it feels worth it. If you are a busy glasser who cannot bother cleaning/drying his binocular frequently, this bino is a perfect option.

Its fully argon-purged lenses ward off moisture, dust, rust, and debris with ease. And, its scratch-resistant ArmorTek coating protects the outer surface of lenses. Even if you use your vortex razor UHD 18×56 binocular on rainy days, it won’t get affected.

The massive 56mm lenses are O-ring sealed that keep the prism system safe and don’t let any impurity barge in.

Moreover, the long-lasting lens and ocular covers that come in the package help you store your binoculars easily. When you don’t use your vortex UHD binocular, close its lens and ocular covers, place it in the carry bag, and store it coolly.

Cruising, kayaking, snorkeling, and surfing; when it comes to water sports, the options are endless. And when we get to see a vast region of the sea with utmost clarity, the enthusiasm boosts up quickly.
