What Makes Nikon Prostaff 3S Worth Your Money?

1. Compact and durable bodies

So far, Japanese products are famous for their high-quality and built-to-last construction. This pair of Nikon Prostaff 3S binoculars are no exception.

Coming at standard size for multiple purposes from spectator sports to nature observation, the unit is as light as 565g for Nikon Prostaff 3S 8×42 and 575g for Nikon Prostaff 3S 10×42.

You can easily put the binoculars inside your bag for picnics or hunting games, or carry them around your neck without causing any neck strain or inconvenience.

2. High magnifications

A rule of thumb in terms of optical tools: The higher magnification results in a closer and more detailed view.

However, there is no need to invest in such a high magnification. Otherwise, your binoculars become heavy and bulky. For birding or hunting purposes, the magnification within 6x-10x is acceptable.

Exciting enough, Nikon Prostaff 3S offers two magnification ranges to choose from: 8x and 10x without sacrificing the weight of whole body. This Nikon Prostaff is still compact.

3. Wide and comfort field of view

Generally, the larger magnification means the narrower field of view.

Excitingly, Nikon Prostaff 3S features both high magnification and large view ranges: 122m out of 1,000m (10×42) and 126m out of 1,000m (8×42.)

This is mostly thanks to the 42-mm objectives lens; wide apparent angle; and the smart construction of Nikon Prostaff 3s.

In addition, the eye relief is long and the exit pupil is large to offer a better field of view, even when you are wearing glasses.

4. Clear vision through multi-coated lenses

The silver-alloy roof prism is another plus.

Not only does this high-end prism reduce the weight and size of the binoculars, but it also provides a clearer view. Built with multi-coated lenses and arsenic-free glass, the prism allows the light to transfer almost completely through the glass. As a result, you can expect a visible light spectrum and brighter images.

5. Waterproof and fog proof

The Nikon Prostaff 3S is feature-rich. Not to mention, it enhances the optical performance in case of outdoor activities.

This optical has a nitrogen gas-filled system and O-ring seals, helping to resist to fog or mold. Moreover, the whole body of Nikon Prostaff 3S is rubber-armored to prevent slips and water from damaging the body.

Now you can take the binoculars along for sports events, outdoor games, hiking, or bird-watching at any weather!

There Are Still Things to Think Twice …

Almost all features are good. However, we would not very appreciate its standard diopter adjustment, to be specific, the center focus.

During our tests on Nikon Prostaff 3S, we found it hard to adjust the lens and rotate the wheel to get a sharper vision. Even worse, the eyecups might retract prematurely upon twisting and against your eyes whilst.

The price is the second concern. Nike Prostaff 3S is more expensive than other Prostaff models. Hence, consider whether you need such a high magnification and wide field of view before jumping to purchase.

  • Compact construction: Vortex Diamondback vs. Nikon Prostaff 3S: 0-1.

Despite having the similar magnification and diameter of the objectives lens, Nikon Prostaff 3S is a bit smaller than its counterpart. Such small pros do matter when you need to bring the binoculars for outdoor activities.

  • Price:  Vortex Diamondback vs. Nikon Prostaff 3S: 0-1.
