nikon monarch 5 10x42 review

This article outlines the Nikon Monarch 5 10×42  binoculars review based on its specifications, makeup, and features that enhance its usage.

Binoculars come in handy when trying to view an object that is far away and hard to see with the naked eye. They are a preferred choice for many people when compared to other optic instruments such as the telescope; binoculars are less bulky and extremely portable.

The perfect set of binoculars would offer a wide field of view, high magnification properties and the ability to use them without needing to wear glasses. Other things to consider would be how easy it is to carry them around, whether they offer a firm gripping ability or whether they are slippery and added features that ensure their quality and most of the durability.

Best Features of Nikon Monarch 5 10×42 Waterproof Binoculars

Featuring ED (Extra-Low Dispersion) Glass

ED glass is the last glass that is used in optical gadgets to represent the actual color of an object. Thinking back to science class, when white light passed through a prism glass, it is split into the different colors we know today. Usually, when an item is viewed through a regular glass, it will often appear blurry.

The composition of the glass determines how sharp and ‘true’ the image will appear. ED glass significantly reduces the dispersion of color allowing the object of interest to appear in its truest form and lucky for us, the Nikon Monarch 5 10×42 binoculars come equipped with this special glass.

Turn-and-slide rubber eyecups

The Nikon Monarch 5 10×42 binoculars feature eyecups that are made with soft rubber. Setting the preferred eye position is made easier with its turn and slide feature which makes eye positioning easier. The rubber also adds to the comfort with an eye relief of 19.5 mm allowing even those with less than perfect eyesight to enjoy the entire field of view.

Fully Multicoated Eco-glass Lenses

The lenses on the Nikon Monarch 5 binoculars 10×42 are made with an environmentally friendly glass that is both lead and arsenic free. This came as an initiative from Nikon to replace all their gadgets with eco-friendly parts. The lenses come equipped with an anti-reflective coat that reduces lens reflections and is designed to enhance the clarity of the object of interest.

Waterproof and Fogproof

We all know how irritating it gets when driving on a rainy day, and the windshield gets foggy from all the air within. Now imagine trying to capture a moment with your binoculars only to have a fog that keeps reappearing.

The makers of the Nikon Monarch 5 have sucked out all the air from the barrels and have replaced the oxygen with nitrogen gas. This means that the lenses will never fog during use. Air is also prevented from coming as the barrels are tightly sealed. Keep reading this Nikon Monarch 5 10×42 review below discovering more features and specifications.

Frequently Asked Questions (FAQ)

1. What is the major difference between the Nikon’s Monarch models and their Aculon models?

Answer: The main difference is that the Nikon is made with a roof type prism glass whereas the Aculon is made with a Porro prism glass. To explain this further, a prism is a glass that allows us to see the image of interest in its upright position. Without the prism, images would appear upside down like they do when you look at words using a mirror.

The roof prism is smaller and places the eyepieces in front of the lens allowing light to travel in a straight line directly to the eye. The Porro prism requires several surfaces placed away from the eyepieces making light travel in a curved path before reaching the eye. This difference makes the Nikon lighter and smaller than the Aculon.

2. Do I need to wear glasses?

Answer: Depending on how strong you need your glasses to be, you may not need to keep your glasses on when using the Nikon Monarch 5. This is because it offers ten times the magnification and an eye relief of 18.4mm allowing even those who need glasses in everyday situations, whose eyesight is not too forgone, to comfortably view clear images without them.

3. Can I keep my gloves on?

Answer: You can keep your gloves on when using this binocular. The Nikon Monarch 5 contains a focus when that is easy to grip and maneuver while wearing gloves; a bonus for those who go outdoors in cold or freezing weather.
