nikon action ex extreme 10x50


I own many different binoculars from various brands. Each binocular performs differently and has its own advantages over others.

It’s almost impossible to buy every binocular available on the market in order to review it.

But I do my best to buy a new optical instrument as often as I can to see how it performs.

This time I want to review Nikon Action EX 10×50 which is very popular optical instrument.

It’s a classic porro prism binocular and in my opinion very interesting optical device.

Nikon Action EX 10×50 is very different from cheap Chinese binoculars.

Though it’s not cheap, it is reasonably priced and has high-quality optics.

I believe most people can afford it.

Nikon Action EX 10×50 leaves an impression of an optical instrument that delivers sharp and high contrast image.

With such optical instrument you can observe all kinds of forest and field animals, sea or terrestrial objects.

The binocular is highly durable, so you don’t have to worry about any parts of the optical instrument to break easily.

Many people prefer to buy cheap binoculars from China thinking there is no difference between brand and non brand optical instruments.

They don’t realize that the difference is huge. Brand binoculars almost always outperform Chinese binoculars and the same applies to Nikon brand.

It’s one of the best brand binoculars available on the market.

Short Review of Nikon Action EX Extreme 10×50

Inexpensive, universal, full-size binoculars on porro prism with high quality optics, Nikon Action EX Extreme 10×50 is one of the top binoculars I can recommend.

It’s not the best optical instrument in the world. There are binoculars that definitely outperform Nikon Action EX 10×50 in all respects.

But the price will be much higher too.

Nikon Action Extreme 10×50 is a truly multi-purpose binocular with a wide field of view.

It’s not like cheap Chinese binoculars with a narrow field of view and some other underperforming features.

Nikon Action Extreme 10×50 is a waterproof and fogproof in order to avoid condensation on the inner surfaces of the lenses during temperature change, especially when you enter your heated house after cold weather outside.

Nikon Action Extreme 10×50 is one of those binoculars that satisfy these and many other requirements for those looking for an excellent set of optical instrument at an affordable price.

Nikon Action Extreme 10×50 Package

The set includes binoculars, a case, neck strap, lens covers and standard warranty paper and instructions translated into different languages.

The binocular case is made of high quality fabric designed to protect the binoculars from harsh reality and has a company logo on it.

The binoculars fit comfortably inside the case.

Unfortunately, the case does not have its own shoulder strap. it is supposed to be worn around the neck with binoculars itself or attached to your belt.

Both options, in my opinion, are not very successful, but this is better than nothing.

The binocular looks really impressive and beautifully designed with a good looking, solid neck strap with Nikon logo on it.

It is very convenient that the binocular is equipped with eyepiece and lens caps that protect optical parts from possible damage.

Nikon Action Extreme 10×50 Review

Nikon 10×50 binoculars, (magnification power 10 times), with a lens diameter of 50mm, which gives a 50/10 = 5mm exit pupil diameter in the eyepiece and makes the binoculars’ image extremely bright, clear and sharp.

It can used anywhere, even including astronomical observations.

The weight of the binoculars is slightly more than a kilogram, but this only gives it stability during holding and can reduce hand tremor during observations.

Weight aspect is arguable in my opinion. Some users are of a different opinion.

As someone who owns different types of binoculars, I can say binoculars with magnification up to 10 and lens diameter up to 42mm are moderately lightweight and don’t cause hand tremor to the point when binocular’s weight becomes an issue for you as a user.

Of course, image is not as stable as when holding binoculars with magnification 8 with lens diameter up to 30mm that are considered compact optical instruments.

I think when it comes to image stability and ease of use, Nikon Action EX 10×50 is not perfect and not the worst one. I prefer lens diameter up to 42mm.

For example, 10×42 binoculars are the most purchased optical instruments.

They are considered full-size binoculars, deliver bright and clear image and image stability is good.

Magnification Power

When it comes to the magnification power of Nikon Action EX 10×50 I consider this magnification optimal for universal use.

Of course, this is not wide-angle binoculars with magnification 7 or 8, but compared to them, Nikon Action EX 10×50 is just the increase when you can take a closer look at the object of observation without losing much of the viewing area and at the same time it’s still convenient to look through binoculars holding it in your hands for quite a long time without resorting to the help of a tripod.

By the way, mounting Nikon on a tripod is also possible. A special L-adapter is required for mounting which is not expensive at all. You can buy for around $10.

Image Quality

The image produced by Nikon Action EX 10×50 is really impressive. Nikon has multi-coated optics with a green tint on the lenses.

With porro prism, you can see a realistic and three-dimensional image.

Nikon has a sharp and high contrasting image thanks to antireflective aspherical lenses with a pleasant neutral, slightly warm color reproduction, but since the binoculars belong to inexpensive models, the device is not without drawbacks: there is a drop in sharpness at the border of the field of view and chromatic aberrations at the borders of the image.

For example, in some binoculars the image has a yellowish tone which makes these drawbacks not so noticeable.

In Nikon you see those drawbacks but overall they are not critical.

You have to really look through binoculars very carefully to notice chromatic aberration.

In fact, chromatic aberration can be seen in any binocular without ED glass. I notice it in my binoculars sometimes but I really don’t care about it.

It can be critical only if you plan to buy binoculars for bird watching.

Thanks to using in Nikon Action EX 10×50 special porro prisms, users can differentiate the distance between different objects when looking through binoculars.

Only porro prism optical devices can deliver such an image quality and depth of view.



Nikon Action EX 10×50 is Suitable For:

Nikon Action EX 10×50 WP model – This line is designed for active lovers of hunting, fishing, sports, travel.

This binoculars cannot be called particularly lightweight and compact – it weighs about one kilogram, but its big aperture (wide field of view), magnification power, bright and depth image thanks to porro prism covers all drawbacks of Nikon Action EX 10×50.
