Design and Build

Nikon has been a prominent company in the field of cameras that if you ask someone about the brand, the first thing that comes to their minds is the camera. However, there are several gadgets that they also offer and it is equipped with great quality of materials that build their items.

Other gadgets and gears that Nikon offers are binoculars, microscopes, camera lenses, equipment for measurement, scopes, ophthalmic lenses, steppers, and rifle scopes. In this review, we will be discussing the parts of Nikon 7577 Monarch 5 which is one of their notable product in the field of binoculars.

Let’s talk about the body build of the Monarch 5 first. From what we can describe based on our camper’s perspective, it is durable and lightweight. The whole figure of the binocular is supported and covered with a robust rubber which makes it more dependable in wet situations. It prevents the equipment from slipping from your hand during intense weather conditions.

On the other hand, Monarch 5 has a 10x magnification power with an objective size of 42 millimeters. This binocular range is already considered to have a wide capacity. Meaning, it can be used on several types of occasion that needs you to have a clearer quality of image view.

There is a measurement of 18.4 millimeters of eye relief. Just a brief description of these specs, this is the gap between the eyepiece and your eye. You can check our Everything You Need to Know About Binoculars article as we break down each spec and features that a binocular has.

The actual field of view of this binocular is 5.5 degrees while the apparent is 51.3 degrees. The close focus reaches up to 2.5 meters. The lenses are made of eco-glass and are fully multicoated. This has multiple films of anti-reflective coating which is armored on the inner and outer surfaces of the lens. The objective lenses are made with extra-low dispersion(ED) glass making the image of the view captured by the binoculars sharper, clearer, and realistic.

Monarch 5 length is 145 millimeters and weighs 600 grams or an estimate of a pound. Our campers have expressed that the binocular is really lightweight but at the same time, it is compact and sturdy when you hold it.

Although Nikon claims this to be waterproof, we advise you to not completely soak or damp it with water. This is just a warning that we really advise even to your other equipment. This protection ability is mainly to prevent the water and also, fog to enter the insides of the binoculars. This attribute works because it is powered with an O-ring seal which makes the body tight to avoid leaks and air entrance.


Clarity and Brightness

From our testing of this unit of Nikon’s Monarch 5, we confirm that the view is really high quality. As we have mentioned in the Design and Build section of this review, the objective lens is finished with ED glass.

ED glass is a component that diminishes the chromatic aberration or also known as color fringing. This is a common optical difficulty wherein the lenses cannot compress the color wavelengths on a similar focal plane. In the situation of Monarch 5, the image can be seen as clear, detailed, and sharp because of this element.

The way they manufactured this binocular aims to provide vivid details of the view that even those who are wearing prescription glasses can experience this. The eyecups are also a commended feature of the Monarch 5 because it gives an abundant distance from your eyes and eyepiece.

The objective lens is fully coated with multiple sheets of anti-reflective coatings. This coating works to reduce reflection on the lenses by reducing the light it allows to the lenses. The fully multi-coatings are finished on both the internal and external surfaces of the optics. This is one of the best features that the manufacturer instilled in this binocular.

Aside from the objective lens coating, the prism surfaces of this binocular are also enclosed with the dielectric high-reflective multilayer prism coating. It is not only a standard type of anti-reflective coating but the capability of this coat can restrain an almost complete reflection. The performance of this material can regulate the brightness parallel to what we normally see with our eyesight.

In the manner of darker surrounding conditions, the Nikon 7577 Monarch 5 is still usable. Judging from the price, if you compare it to other binocular’s optics, we can say that this is more capable.

Comfort and Ease of Adjustment

If we describe the body of this binocular, we can say that it looks firm and slim compared to other binoculars with the same specs or higher. As per evaluation, the grip makes you feel that it is secured because of the rubber built. It fits perfectly when you hold it.

Apart from the rubber-equipped body of the Monarch 5, the eyecups are also made with rubber with a turn-and-slide function. This type of feature allows the user to adjust the eyecups for appropriate eye relief. With such, it will extend the comfort whenever you use it for a long duration of time.

Aside from the special features we mentioned that Nikon has engineered in this binocular, the focus knob is an added recommended attribute we can praise. Since we are discussing comfort, the said knob is indeed smooth when you twist or adjust it. It’ll give you more ease when you are focusing on a specific object.

Our testers have expressed their admiration for the focus knob as it doesn’t need a lot of effort for you to adjust the view. With a simple rotation of the knob, you can already achieve the clear image you are targeting. It is just totally smooth and precise.

Another thing you should consider is the portability of this equipment. We all know that this is a lightweight binocular with a pound of total weight measurement. It is just a compact gear that you’ll love to carry around without any struggles.



The Nikon 7577 Monarch 5 is a lightweight and durable type of binocular. We recommend this because of the price range and the features it can offer. Other binoculars that have the same price are not really as dependable compared to this unit.

With a good body built and design, you can ensure the safety of this equipment in your grip. And also, it is water and fog-proof which will lessen your binoculars’ vulnerability from rains and fog.
