Vortex Diamondback 10×42 Binoculars are a top-of-the-line product. These binoculars offer a wide field of view and crystal clear optics. The lenses are fully multi coated for maximum light transmission, which helps to eliminate flare and ghosting.

These features make them perfect for bird watching or hunting, where the slightest detail is needed to spot your prey. The Vortex Diamondback 10×42 Binoculars provide excellent magnification with their high power of 42 mm lenses that help provide a crystal clear and sharp image with no eye strain or loss of clarity.

They also have an exceptional clarity and there is minimal color fringing due to the phase coated lenses. They’re optimized with select glass elements to deliver exceptional resolution, cut chromatic aberration, and provide outstanding color fidelity, sharpness, and light transmission.

Light Transmission Rating

If you’re looking for a high-quality, durable, and functional binocular that can be used to study wildlife or sporting events from a distance, the Vortex Diamondback 10×42 might be just what you’re looking for.

This unit boasts fully multi-coated lenses, which give an impressive light transmission rating of 98%, and has a Dielectric coating that allows the user to easily observe in low-light conditions and in all types of weather conditions.

The Vortex Diamondback 10×42 also includes coatings on both sides of the lenses which reduce glare from light sources, so users don’t have to contend with eye fatigue. It also has an Armortek coating that protects the exterior lenses from scratches, dirt, and oil.

Field of View

The field of view is one of the most important features for a scope, especially when you are trying to catch a bird in flight. Field of view is the width across your vision from left to right.

A large field of view like the Vortex Diamondback’s 330 feet @ 1000 yards will make it easier for you to see a bird’s wing flutter and watch it fly. The shorter the field of view, the more difficult it can be to focus on small objects at great distances.

Focusing System

Simply put, a focus system allows you more control over your binoculars, allowing more precise focusing. Whether you’re hunting or birding, there are some features that any good quality binocular should have. The focus system is one of those features.

This will play a vital role in ensuring that you get an image that is very clear and sharp not just for normal viewing but also during use in low light conditions. The vortex diamondbacks​​​​​​​ have a smooth motion for focusing, that is very easy to use even if wearing gloves, and it feels firm and responsive. 

Waterproof & Fogproof

Are the Vortex Diamondback 10×42 HD Binoculars waterproof and fogproof? Yes, they are both. The body of these binoculars is sealed against water with a rubber O-ring to prevent any moisture from getting inside and causing problems.

Fogging can also be an issue with optics in general because of their design. To combat this problem, the Vortex binoculars have been treated with antifog coatings on all air-to-glass surfaces that prevents condensation​​​​​​​. The rubber O-ring, and the coated lenses will also protect them from moisture, dirt, dust, and scratches.

This coating also helps prevent internal reflections from affecting image quality. Vortex has even gone so far as to provide a lifetime warranty on their products in case they do become damaged due to water or other outside forces such as drops​​​​​​​.

First Impressions

The Diamondback 10×42 Binoculars feature a rubber-armored housing that is extremely rugged and durable. It’s also very ergonomic, with a nice full grip and twist-up eye cups.

It has smooth rotation on both axes, which makes it easy to track wildlife – even in rapid sequence – without moving your hands or having to reposition your head. The binoculars have a 42 mm objective lens, giving you a wide bright image in low-light situations.

They have a center focus knob with a 10:1 zoom ratio on the right-hand side of the body. The focusing is very smooth and precise on these binoculars, making them easy to use whether on a quick outing or during extended viewing sessions.

They have rubberized armor on the exterior that helps with shock protection and provides a good tactile feel that makes it easy to use. These binoculars also feature an angle of view of 6.3 degrees, which is comparable to many more expensive options! 

Exploring the Vortex Diamondback

What really set them apart was their relatively simple, clean design and dedication to manufacturing quality products at an affordable price.

1. The first thing I like about these binoculars is how easy it is to use them. You can focus on what you want quickly without having to mess with any settings or controls; this is due in part because they come with an adjustable diopter ring which makes them very easy to use. The rings are easy to move, even when you have gloves on. This will help you see everything better and makes observing more enjoyable because there’s no need to worry about sun glare hurting your eyes anymore!

2. They are lightweight, weighing in at 21 ounces; I don’t like it when the weight of my binoculars causes me neck pain or gets uncomfortable during long periods of observation.

3. They are easy to adjust for different sized heads, which is a problem with other brands.

4. It’s great that the binoculars come with a neck strap and carrying case, making them perfect for travelling!


I recently tested this model extensively during my yearly local excursion to one of my favorite birding spots. We always make sure to visit during the spring and fall migration seasons.

We saw dozens of different types of birds, and other animals. As for the Vortex Diamondback HD 10×42 binoculars performance, I was very impressed with them under these demanding conditions.

They are not only high quality, but also durable and easy to use, making them perfect for outdoor observations. The binoculars are quite compact, which makes them easy to move around with.

The lightweight design allows for better control of your movements when looking in the sky. After testing them for almost a month, and putting them through torture, I can honestly say that they are durable enough to last us a long time, especially under harsh conditions.

As for price, it is right in line with many types of binoculars available in the market nowadays. They are not the cheapest, but they come at an affordable price point.

What Could Be Improved

The Vortex Diamondback Binoculars are a great pair at a great price. The binoculars have a good size and feel in your hand, plus they’re easy to adjust.

The Vortex Diamondback also has good clarity due to the high quality lenses. However, the Vortex Diamondback does not have any image stabilization, which can be an issue when using at high magnifications where any shake is exaggerated.

If you don’t plan on going into really low light conditions, then you will be okay without it, but it is something that needs to be considered before buying this pair of binoculars.
