Hilkinson Quickscope 6×20

It’s not meant to compete with more traditional binoculars; instead, it’s designed to provide clear, magnified views of small, close-up items, with a close focus range of just 25 cm.

It’s brilliant for looking at insects, birds, plants, and animals. And if you’re interested in seeing the wildlife inside a small backyard, you can do that too.


Clarity is an excellent value, despite its high price tag. Its handling is easy to use once you get used to using it.

Hawke NatureTrek 10×25

The Hawke Naturetrek provides high-quality optical performance at an affordable price.

Field of View

We found that the 10×25 lens had a narrower viewing angle than the 8×20 lenses, but that didn’t affect its performance too much. It performed well even when shooting at dawn or dusk, and was good for capturing images of birds and other wildlife.


The image from the Nikon 8×25 ED is sharper than the one from the Canon 8×25 ED, but Hawke has minimized color fringing and distortion quite well.

Exit Pupil

If you want wider views and a bigger viewfinder, NatureTrek has both an 8×24 and 8×32 lens.


One of its strengths is its ease of use. It’s light, has an ergonomic design, and is waterproof, with flip-out eyecups and a smooth, easy-to-turn focusing ring.

Eye Relief

The 13mm eye relief makes it comfortable, too.

Close Focus

It has a minimum focusing distance of 5 meters (16 feet), which makes it suitable for people who want to take pictures from far away, but not too far away. However, it’s best suited for people who enjoy taking photos of things up close.

what is highest power monocular

What Is Highest Power Monocular?

Viking 8×25 ED

While this price may seem high at first glance, it’s actually a good deal considering that the Viking 8x 25 ED is one of the most affordable monoculars available today using extra-low dispersion (ED) lenses.

This reduces chromatic aberrations (color fringing), which makes for a sharper, clearer picture.


Because of this, the 8×25 HD delivers the best image quality we’ve ever experienced from an ultrawide angle lens at this price point, especially in bright light when color fringing is most noticeable.

We found the 8×25 ED perfect for birding during the day, but it also worked well at night.


It has a lower power rating than some of the higher-powered options but is more versatile.


It’s a bit heavier than the other 25 mm binoculars, but the all-metallic construction felt sturdy, and we found the focusing ring stiff when trying to adjust for distant objects.

It’s water resistant and comes with a protective hard shell case and a shoulder strap.

We think this is an excellent choice for serious birdwatchers, nature lovers, and hikers who want good performance at a reasonable price.

Key Specification

  • 8x magnification
  • A 25mm objective lens
  • Fully coated ED lenses
  • Field of View: 6.8 degrees
  • Exit Pupil: 2.5mm
  • Eye Relief: 15.3mm
  • Close Focus: 1.6m;
  • Waterproofing
  • Accessories Included: Soft bag, strap
  • Length: 11.1cm
  • Weight: 162 grams

Opticron Oregon 4 PC Oasis 10×42

Even though it’s larger and heavier than the compact monoculars, this one makes up for its extra size by making the added weight worthwhile.

Magnification and Lens

With the larger objective lenses and 10 times magnification, you can see distant objects clearly even when there isn’t enough light for the smaller ones.


And even though there isn’t an ED glass at this price range, the view through the lens is still impressively bright, which makes it ideal for bird watching, sports, or nature photography.


It has a good balance between size and usability, making it easy to hold and operate with one hand. You can easily adjust the focusing distance by turning the dial on the top.

Eye Relief

It has a twist-out eyecup for good 18 millimeters of the distance between the lens and your eyes, and it comes with a nitrogen-filled anti-fog chamber to keep things clear. It’s an affordable monocular that is a real pleasure to use.

Key Specs

  • 10x magnification
  • 42mm objective lens
  • BAK4 prism
  • Fully-Coated Lenses
  • Field of View: 6 degrees
  • Exit Pupil: 4.2mm
  • Eye Relief: 18mm
  • Close Focus: 1.8 meters
  • Waterproofing: Shockproof construction, nitrogen filled
  • Accessories Included: Soft case, strap
  • Length: 14.7cm
  • Weight: 334 grams


The highest power monoculars are those with the largest aperture. The larger the diameter of the objective lens, the more light it can gather and focus on a distant object.
