Description of Nikon Action EX Binoculars

The Action Extreme series by Nikon offers binoculars for wide varieties of use, from hunting, birdwatching to astronomy and marine applications. They offer extreme durability and great optical performance. Porro prism system helps with better light transmission together with multi-coated system. They are well protected with O-ring seals and filled with nitrogen gas to prevent internal condensation. They are also equipped with rubber armouring and eyecups and provided with central focusing mechanism for quick adjustments. The 7x35 model prides itself with the widest field of view (163m) and 16x50 model offers incredible power for long distance scanning of larger areas or sky-gazing.

Basic features

Action EX models are all enclosed in rubber armouring that is hard and thick to protect these binoculars against impacts. The waterproof construction is the result of tight O-seals and hard aluminum body that makes the construction extremely durable and corrosion-free. The construction is also purged with Nitrogen gas to prevent the formation of condensation and molding. They are able to withstand the pressure in the water for 5 minutes if submerged or in case of accidental fall. This makes Action EX models incredibly well protected even in the most severe environments. The binoculars are equipped with tripod adaptable screw, very convenient for models with bigger magnifications that usually make less steady images.

Optical properties

Nikon Action EX series offers incredibly bright images thanks to Porro prism system, which combined BaK-4 prisms offer great light transmission and sharp, crisp image. The lenses have multi-layers of high-quality coatings applied on the surfaces to help with better transmittance. They also have an anti-reflective ability, to eliminate glaring, internal reflections and chromatic aberration that distracts the perfect resolution and colors. For focusing, the Action EX series uses central focusing mechanism. The long focusing throw offers fine-tune although this means the mechanism is less quick, but the smooth turn of the wheel helps with comfortable adjustments. The knob is integrated into the hinge and is rugged to prevent sudden slipping. To eliminate differences between both eyes, there is diopter set below the right-eye eyecup. The eyecups are multi-positioned with click-stops that allow you to set perfect distance for your eyes from the ocular lenses which helps to eliminate vignetting that can compromise the clear viewing.

Accessories

The Action EX comes in a padded case for storage and protection and neckstrap for carrying. There are also objective lens covers and rainguards for additional protection of the lenses.

VIDEO

Marine binoculars are designed to be used at sea, where magnification over 7x usually causes seasickness. These binoculars also offer great protection against the water and are not sensitive to high temperatures or their housing being exposed to sunlight.

Many of these binoculars also include a compass or some kind of reticle for range finding.

General features:

Waterproof housing
Porro prism design
7x magnification
Individual focusing
Compass
A reticle for range estimations

Marine Binoculars with a Compass

At sea, having a compass is very useful for navigating and coordinating positions. To combine the compass and binoculars in one device seemed logical so that you do not have two things at once in your hands.

There are 2 principles of displaying the compass reading:

An analog scale on the bottom of the field of view of the compass with degrees written on (can be illuminated in more expensive models)
The digital display in the middle of the field of view (push the button to read the degrees, transparent display, which reduces transmittance. The compass is easier to use if it displays degrees in the middle).

Built-in Rangefinder

Rangefinding Binoculars are more or less all very similar- having a scale in the middle of the field of view, with which you can calculate the distance to the observed objects if you know their size.

Good „miling“ requires a lot of experience and good prediction. It is the same principle as with tactical riflescopes. The scale is milliradian.

For now, there are no marine binoculars available with the laser rangefinder.

Why is 7x50 the most common Marine Binoculars configuration?

The 7x50 has established itself as a golden standard. While looking through the binoculars the 7x magnification does not shake the image to the point of getting seasickness, and our brains can normally compensate it.

Most of them have Porro prism because it makes them easier to seal and individual focus for each eye separately. 50 mm objective lens and 7x magnification give the 7 mm exit pupil, which is the most comfortable to use as it eliminates the trembling and allows us to always see a "full" picture.

Marine Binoculars with Image Stabilization and Individual Focusing

Image Stabilization

Most modern marine binoculars have this function, as it is possible to use higher magnification for better details. Normally, such binoculars are larger, heavier, and more expensive.

They usually do not offer as good resolution as the classic ones with the same magnification. It is also a major weakness that they are not as reliable (less permeable if they fall into the sea and less resistant to falls) and bumps and are less bright.

They do, however, offer the use of higher magnification on moving boats due to their ability to stabilize the image.

Individual Focusing

This feature is extremely common in this type of binoculars, as it also achieves the best water tightness.

Steiner Marine Binoculars

In Europe, Steiner has become an established provider of marine binocular to the extent that nobody else in the premium class actually produces them anymore (Zeiss, Leica, Swarovski ...).

Steiner has 3 series of this type of binoculars.

Low Light Binoculars

Configuration 7x50 and Porro prism are optimal because of a 7mm exit pupil, good light transmission, and focusing separated for each eye.

All these features mean that this type of binoculars is also the best choice for observing in the dark.

Due to all of the above configurations, they are perfect for dusk and dawn - however, they are not popular in hunting due to their special appearance, size, and inadequate colors.
