Binocular Battle: Nikon Monarch 7 vs. Vortex Viper HD

Monarch 7 vs Viper

It’s tough to choose between binoculars, especially when you’re new to the world that comes along with these types of optic products, and honestly, there’s a lot to choose from- whether it’s lens type, the manufacturer, specific specifications, terrain resistance, build strength, magnification, or even just the brand- which means that you’ve got your work cut out for you.

Several brands, especially Nikon, have a rich history and reputation that makes NOT purchasing a Nikon product difficult. In fact, Nikon products usually have such high quality lenses at more affordable prices with unbeatable warranties, which generally makes it a smart decision.

Nevertheless, there are a wide variety of extraordinarily high quality varieties of binoculars out there and the Vortex Viper HD are no different. If you’re willing to spend a little bit more, you might very well enjoy everything that these top of the line binoculars have to offer.

Nikon Monarch 7 Review

Size and Ergonomics

One thing that you would immediately note about the Monarch 7 series is that they are considerably bigger and clunkier than most Monarch brand binoculars. Anyone with experience with Nikon products knows that the Monarch brand is the “sportier” line of Nikon optics, so one might expect a more compact experience.

Optical Performance

However, the optics on this particular Nikon model is outmatched by very few products. While Nikon series binoculars are known as the “middle ground” of binoculars because they use roof prisms that are more durable than higher end porro prisms, the coatings that Nikon puts on its binoculars are spectacular- an initial silver coating to give them more magnification and brightness in low light situations, and a coating to help with high light situations and focusing- giving you excellent quality in lower end glass- and it’s typically reflected in the price.

Another thing about the Monarch 7 series is that they have an excellent field of vision and provide spectacular watch-ability if you’re following wildlife, or going on a hike. We recommend 8 times magnification, simply because anything else is overkill, but these provide excellent color saturation, are completely nature-proof, fog proof, water proof and highly durable, have no chromatic aberration to distort your view and are great to use with glasses- which is extremely important.

Match that with the field of view and the excellent image quality and detail that these monarch products bring, and you’ll be pleased with the quality of these binoculars. Complete with ocular lens covers and objective lens covers, with an armored body, case and neck strap, you’ll never have to worry about breaking them.


That being said, they are a little bulkier than they have to be, and the lens covers are looser than they probably should be. While Nikon binoculars are great out of the box for use, the accessories that come with the binoculars don’t quite fit the bill. With no real instruction, you’re going to have to be pretty crafty to get everything put together on these ones.

Vortex Viper HD Review

Size and Ergonomics

“Vortex Optics” was once a kind of a no-man’s name when it comes to optics- completely overshadowed by the bigger, more popular and historied brands. That being said, they’ve become very popular in recent years, thanks to great design and value. They are probably the most lightweight varieties out there, with a rubberized body to increase the grip you get with actual thumb and finger grips, and they’re just as durable against drops and breakages as the Nikon products are.

Optical Performance

While the optics aren’t quite as coated as the Nikon Monarch variety, they do have excellent low dispersion lenses and extremely high density glass that produces some of the best and sharpest images with great contrast and focus ability.

Vortex actually uses the same brands of viewing glasses (in HD clarity) as other optics companies do, so they come in very close competition with competitors, and provide great visage in low light situations compared to Nikon or other brands. With this, the Vortex product also offers a huge variety of magnifications and a very similar warranty to Nikon (but you’ll notice most high-end brands doing this these days too) so you’ll hardly see a difference between these two products except in size, shape, weight, and build.


Some of the major problems with the Vortex Viper HD are that they haven’t got the BEST field of view– while the view is great, it’s not as wide as some other brands.

Additionally, some have complained that the eye cups are sticky and hard to use and open when you’re fumbling to view a bird or animal at a distance that’s on the move, and the eye relief isn’t as good as Nikon brands are- which is pretty typical in side by side comparisons.

They aren’t terribly expensive, but they are a few hundred higher than your typical Nikon Monarch 7, while the Monarch cases blow the Vortex Viper cases out of the water.

Which Should You Choose?

It really depends what you’re looking for in binoculars. If you’d prefer eye relief, a cheaper price, and around the same quality lenses all around, you’ll probably end up going with the Nikon Monarch varieties. While both have very similar warranties and optic glasses, the Monarch brand offers a higher field of vision (which is very important to hikers and nature watchers) and double coating that makes their optics similar to porros prisms. That being said, if you’re not worried about price, you might end up going with the Vortex brand because they’re lighter weight and much easier to carry around than the Monarch brands, which is a huge draw for anyone that’s moving around a lot. While both have pretty similar lens cover issues, the Monarch brand offers better eye relief (another notorious Nikon feature) perfect for anyone that’s stuck wearing glasses. The all important decision comes down to your personal preference, but most would probably end up going with the storied history of Nikon products, mostly because a pair of Monarchs will probably cost around 400 dollars while a similar pair of Vortex Viper HD lenses would end up costing approximately 200 dollars more. If accessories are important, the case is better on the Nikon varieties, but you’ll probably end up buying a newer, more adjustable strap in the end anyways.

Go with what feels right for YOU, because you can’t go wrong with lifetime guaranteed full-coverage warranties.

Buying Binoculars: The Choice is Clear

Vintage BinocularsBinoculars are perhaps some of the most popular and useful optical instruments that are used for a variety of different purposes. Different types of binoculars are available depending on your activity, coming at various price points.

Novices will look at all the binoculars and say they all look the same – but each pair has its own specialty, depth of application, and quality. Binoculars and optics are one of the few types of products where quality is paramount, and to get the best binoculars for the money, you will truly get what you pay for. This makes it necessary to understand the basic specifications of a pair of binoculars, which will help you choose the right pair for your specific need.

Understand the Specifications


Binoculars are designated with two numbers separated by an X. For example: an 8×42 pair or an 10×50 pair. The first number of this designation is known as magnification or the power of the binoculars. A 10x pair means that the object you view through the binoculars will be optically magnified 10 times that of the naked eye.

However, it is important to note here that higher magnifications do not represent a better pair, the best magnification depends on the application of use. Very high magnification lenses come with certain drawbacks – shaky images due to hand movements, narrow field of view and darker images.

Objective Lens

The second number in the designation is the diameter of the objective lens. An objective lens is the outermost lens in a pair of binoculars, which gathers incoming light. The diameter of the objective lens represents the light collecting power of the lens. For a given magnification, a higher objective lens diameter means greater light collecting power and thus brighter and higher resolution images. However, a larger objective lens means a heavier pair of binoculars.

Field of View

The field of view of binoculars is the total visible width at a distance of 1000 feet or meters. The field of view determines the area of visibility through a pair. The greater the field of view, greater is the end to end width of visibility. The field of view is related to the magnification – higher the magnification, lower is the field of view and vice versa.

Exit Pupil

The exit pupil represents the size of the light circle at the eye piece of the binoculars. Standard exit pupil sizes are calculated by dividing the objective lens diameter of a pair by its magnification – a 7×21 pair will have an exit pupil of 3mm. The bigger the exit pupil, the brighter is the image viewed.

Relative Brightness Factor

The relative brightness factor is a number that gives you a rough idea of the brightness of the image captured by the binoculars. Numerically, the RBF is the square of the Exit Pupil. Thus an exit pupil of 4mm represents an RBF of 16. The RBF does not factor in the various measures taken to increase brightness such as lens coatings; number of lenses used etc and is only a representative number.

Twilight Factor

The Twilight Factor is a relative number that describes viewing under low light conditions. Numerically, the twilight factor is the square root of the magnification multiplied by the objective. For example, 7×21 binoculars will have a twilight factor of 12. The higher the twilight factor, the better is the visibility in low light.


Binoculars have a pair of prisms that allow light to pass through them. Based on the orientation of the prisms, Binoculars are of two types – Porro and Roof (Dach). Porro prism binoculars are less expensive and offer a wider field of view. Roof prism binoculars are much smaller and sleeker than their Porro counterparts making them more compact.

Lens Coatings

Lens coatings are used to minimize reflections off the surfaces of lenses and increase the transmission of light. Usually all the faces of the lenses are coated to increase transmission. However, in some cheaper binoculars, only the outer faces might be coated. The best binoculars will have fully multi coated lenses to provide the sharpest, brightest image possible.

Lens coatings are of the following types:

  • Fully Multicoated – All faces have multiple layers of coating (3-5 layers)
  • Fully Coated – All faces have a single later of coating
  • Coated – One of more faces have a single layer of coating

Choose Binoculars Based on the Activity

While choosing a pair of binoculars, always remember the purpose of its use. Binoculars are used for a number of activities such as bird watching, hunting, sky watching, watching athletic competitions, and even for concerts. Each activity has its own special requirements in binoculars to get the best experience.

Higher magnification does not mean better binoculars. A lot of other factors such as objective lens diameter, field of view, brightness factor have to be taken into consideration. The larger the magnification, the lower is the field of view and stability of the images decreases. Choose binoculars with just enough magnification, a sufficient field of view and an objective lens diameter. Higher objective lens diameters lead to greater light collection – for better and brighter images.

Bird Watching

8x binoculars are considered the best pair to buy for bird watching, as they offer the following advantages:

  • Offer a sufficiently wide field of view
  • Eye relief and sufficient magnification
  • Stable image without the use of a tripod

Bird watching requires constant binocular movement. Thus, having a very high magnification pair will restrict your motion, as you will be forced to use a tripod to get stable images. Also, the wider the field of view, the easier it gets to follow the bird.

Choose a pair of binoculars that offers a good field of view at 7x or 8x magnification. For viewing birds at reservoirs, 10x or 12x magnification binoculars with a tripod are the best choices.


When choosing binoculars for hunting, it is imperative that you choose optics with excellent low light performance. The prey is usually most active during dusk and dawn and these are the times you will have a good chance for a kill, which is why hunters usually prefer high objectives of around 42-50mm.

The magnification of the binoculars depends on the terrain that you are hunting in. For a terrain full of trees, you will do better with wider field view binoculars of around 7x or 8x. If you are hunting in an open terrain, larger magnification 10x binoculars are a good choice.

Sky Watching

Sky watching or stargazing requires different binoculars depending on what you intend to view. For example if you want to see the moon, even normal compact binoculars will be able to show you the surface clearly. For viewing planets like Jupiter and Saturn, a minimum of 10x magnification is required.

For night sky viewing, the greater the size of the objective the better. Since the night sky is very dimly lit, you need your binoculars to gather all the light it can for better viewing. Binoculars with objectives of 50mm to 80mm are generally picked.
