Nikon Aculon 16×50 Review

Nikon Aculon 16×50 belongs to medium class binoculars. The binocular produces high quality, clear, sharp and colorful image.

Medium class doesn’t mean it’s not a high-end binocular. All binoculars from Nikon are very good products.

The only reason Nikon Aculon 16×50 is not high class binocular is because it’s not waterproof/fog proof optical instrument.

It’s not a big problem because the price is not high too considering that it’s a high-power binocular that has magnification 16x.

Nikon Aculon 16×50 is suitable for general use at home, sporting events, nature watching.

For travel and hunting I would recommend choosing a binocular with magnification 8x or 10x, preferably waterproof and fog proof.

Nikon Aculon 16×50 produces an excellent image thanks to objective size being 50mm.

Such a size allows enough light to pass through binoculars and as a result you get clear and bright image.

Even when weather is cloudy and at night times. Depth of view is good too and without any image distortion.

Nikon uses its own brand glass known as Eco-Glass lenses that deliver astonishing clarity.

Thanks to objective lens size being 50mm you get brighter image and can view objects even in cloudy weather or at night time.

Eco Glass is a good addition to BAK-4 prism which allows to deliver high-contrast image without any distortion.

Protective rubber armoring on Nikon Aculon 16×50 provides a comfortable slip-resistant grip which is great in its own.

But unfortunately, Nikon Aculon is not shock proof. So, you need to be careful when using or holding it in your hands.




Eye Relief or suitability for eyeglass wearers

Fold-down rubber eyecups allow to use Nikon Aculon 16×50 without eyeglasses. But it may note be suitable for every eyeglass wearer.

Because the best for eyeglass wearers would be binoculars with eye relief 15mm or even 18mm. Nikon Aculon 16×50 has eye relief only 12,6mm.

Most of the time you can easily use binoculars without eyeglasses.

Because eyecups can be adjusted to adjust the distance between your eyes and binocular’s exit pupils.

If you have serious problems with your eyesight then you need to look through binoculars over your glasses and adjust the distance using binoculars eyecups.



Tripod adaptability

Nikon Aculon 16×50 is tripod adaptable. It’s relatively lightweight and can be used without a tripod.

But if you need to view objects like Moon or planets then you better use it with a tripod for a more stable image.



Weight – Ease of use

Nikon Aculon 16×50 is only 925 gr. which is not a lot compared to other high power binoculars.

To adjust the binocular to view objects you just use central focus wheel and right diopter that are smooth and easy to use.

Image is relatively stable because binocular is relatively lightweight.




Field of view

Field of view in Nikon Aculon 16×50 is 4.2° (220 feet / 1000 yds) which is very nice compared to other high power binoculars.

Viewing experience with such a binocular is more than satisfactory. Because field of view is one of the most important aspects of any binocular.

I would say whatever binocular you choose, 3° field of view is the minimum for comfortable viewing experience.



Waterproof/Fog proof

In humid environment using Nikon Aculon 16×50 can cause an issue which is not so good to be honest.

But we must also understand that Nikon Aculon delivers high quality image thanks to high quality lens and prism used in the binocular.

Considering that the price is not high at all I believe it’s a good purchase.

If you are an active traveller and plan to use Nikon Aculon in various weather conditions then you better choose another binocular, such as

  • Vortex Optics Vulture HD Binoculars 15×56
  • Nikon 7247 Action 16×50 EX Extreme All-Terrain Binocular
  • Levenhuk Karma PRO 16×42 Waterproof Fogproof Binoculars



Lens coating

Nikon Aculon 16×50 has aspherical multicoated-Eco-Glass lenses which provides high quality image. But it’s not fully multi-coated.

Normally, binoculars with magnification up to 12x have fully multicoated lenses. In high power binoculars it becomes technically difficult to achieve.

Still image quality is very good in Aculon thanks to using Nikon’s branded Eco-Glass technology.



Prism type – Optics quality

Nikon Aculon 16×50 has poor prism which provides good depth of view known as three-dimensional image.

The image in such binoculars is more interesting than in roof prism thanks to porro prism technology.

Of course, not all binoculars have the same level of depth of view. It depends on the brand.

When it comes to Nikon brand it’s always high quality image thanks to experience of Nikon in the field of optics.


nikon aculon accessories



Nikon ACULON 16X50 comes in a solid box with objective lens caps, quality strap, cleaning wipe, user guide, tripod adapter and warranty.

BTW, not all binoculars come with tripod adapter. You have to buy it separately which will cost you around $10-$20.

Fortunately, since Nikon Aculon 16×50 is a high-power binocular and comes with a free tripod.




Nikon Aculon 16×50 has a very affordable price which is $111. I think it’s more than affordable for most people.

Because high power binoculars with magnification 15x and above are expensive.

Nikon which has magnification 16x is pretty powerful and provides high quality image. Plus it comes with accessories including tripod adapter.

I believe the price is very friendly and most people can afford it.



Magnification 16x VS 20x

From my personal experience with optics and optical instruments, such as binoculars I believe for those looking for high power binoculars with magnification 15x, 16x 20x, 25x, magnification 15x and 16x is the best option.

The most purchased one is 20x. The difference between 15x or 16x and 20x in terms of magnification power is not big to be honest.

But binocular 20x is bulky and most of the time it needs tripod. Since binocular is bulky you get shaky image as a result.

That’s why binocular 15x and 16x are the best optical instruments. Especially they are good and suitable for long observation sessions.

Because they are:

  • Relatively Lightweight
  • Have wider field of view
  • Have steady image



Overall quality

Overall quality of Nikon Aculon 16×50 is very good. The optics quality, binocular’s body and design, image quality, field of view, accessories.

All of this is more than satisfactory. I definitely recommend Nikon ACULON 16×50 though it’s not waterproof/ fog proof.

It’s an excellent buy especially if you buy it for general use.

    Hi Adam, I chanced upon your website searching the web for Nikon Aculon 10-22×50 zoom binocular’s worthiness. I have to say your take on the matter has transformed my view about them. Fixed mag ones it will be. I plan to use them for bird watching and safaris to the national parks in India. Reading up on your website Aculon 16×50 seems pretty good but not fog/water resistant and maybe on a heavier side. Should I go for Nikon 7245 action ex extreme 10×50 (or maybe 7246 12×50)considering portability, image clarity and fog/water resistance porro prism. Or a much costlier monarch 7541 with roof prisms and much better build? Also prostaffs 10×42 seems to be a viable option.

      Hi Somak,

      Thank you for the comment. Yes, zoom binoculars are not worth your money. It’s worthless. It’s really hard to find all-purpose binoculars. I personally have many binoculars with different magnifications, such as 4x, 8x, 10x, 12x, 20x. I have many because one binocular can’t satisfy all your needs. For bird watching you better choose wide field of view binoculars and selection is really huge. I would recommend:

      Nikon Trailblazer 8×25 ATB Binoculars
      Bushnell Legend Ultra HD Compact Folding Roof Prism Binoculars, 10×25-mm
      Wingspan Optics FieldView 8X32
      Vortex Optics Diamondback Roof Prism 8×28 or 8×32

      These are waterproof and fog proof and lighweight.

      Nikon Prostaff 3S 8×42 is a good option. It’s waterproof and fog proof. But it’s not lighweight.

      These will do well for bird watching. For safaris you better choose magnification 10x. Same binoculars mentioned above have 10x magnification as well. But for the most part 8x binoculars will satisfy your needs. They are powerful, and lightweight.

      I wouldn’t recommend porro prism because they are bulky for bird watching.

      If you still need powerful binoculars for viewing distant objects, the best powerful binocular and lightweight I can recommend Levenhuk Karma PRO 16×42 Waterproof Fogproof Binoculars.

      The last one is Canon 15×50 Image Stabilization All Weather Binoculars. It’s expensive but it’s a great optical instrument for those who can afford it. For more info read here

      You can find all those binoculars on

        Hi Adam,
        Thanks for your kind reply. So probably for bird watching I should probably keep one set of lighter ones. For safaris, if ~1 kg is not huge deal, and if I want to stick to Nikon, I am seeing on Amazon India in my budget range(~ Rs15,000), that Nikon prostaff 3s or 7s (10×42/50) are available which are fog and water resistant. They have roof prisms, so bit lighter. In the same price point (ruling out Aculons) I am getting Nikon Action EX extremes 10/12x50s. These are also nitrogen filled fog/water resistant, but with porro prisms, so bit heavier. Guess my questions is if I have to choose between these two classes, which one would be a better choice. I read through your article about binocular optics details which stated porro ones create a better 3D scopic images than roof prisms, so I am tilting towards action extreme ones, is that wise?

        • Adam says:

          Porro prism action extreme is a good one. But porro prism are a little bulky which causes hand shaking when looking through binoculars. From my experience I would recommend to choose binoculars with magnification 8x. For example, 8×25, 8×30, 8×32. These are lightweight.

          If you need a powerful Nikon binocular I would recommend Nikon 7247 Action 16×50 EX Extreme All-Terrain Binocular. It’s waterproof, fog proof and porro binocular.

          If magnification power is not so critical I would recommend 8x binoculars because they have wider field of view than 10x binoculars and pretty powerful.

          For lightweight porro binoculars you choose Nikon 7237 Action 7×35 EX Extreme All-Terrain Binocular
