Manufacturing quality and ergonomics

The Nikon Sportstar EX 10×25 is designed to withstand the elements such as dust, dirt, etc., and even bad weather. These binoculars are not afraid of water and remain in perfect condition even after immersion (up to 2 meters of water) for up to 5 minutes.

If you practice water sports, this waterproofness makes the Sportstar EX 10×25 a perfect choice.

These all-weather binoculars can also be used on a daily basis, both indoors and outdoors. Besides their anti-fog, compact and lightweight design, the Nikon Sportstar EX 10×25 has a folding function, which makes it easy to store and take them with you whether you are going to a picnic, a hike or at a show.

Also, the Sportstar EX 10×25 binoculars are comfortable to use. Not only because they are covered with ergonomic rubber armor to ensure you have the firmest grip possible even in bad weather but also because their controls are well positioned. Particularly, the central focus wheel is user-friendly and can be adjusted quickly and easily.

Moreover, if you wear glasses, you will be reassured to know that the rotating and sliding rubber eyecups of these binoculars can be adjusted according to your eyes to adapt to them without limiting your vision.

Optical performance and possible uses

Nikon Sportstar EX 10×25’s feature 25mm objective diameters, excellent quality roof prisms and multi-coated lenses to capture and utilize as much light as possible. That’s because while the large objective lens collects extra light, the multi-coated lens coating ensures minimal reflection, resulting in bright, vivid images even in poor lighting.

These binoculars have 10x magnification and can therefore make your subjects appear 10 times closer. If you do a lot of long-distance viewing and want to see more detail from farther away, the Sportstar EX 10×25 is a good choice.

They also have a wide field of view that lets you see more of the area surrounding the observed subjects. This is particularly interesting for observing several subjects at the same time or fast-moving objects.

That said, to get a closer look at a subject in intricate detail, you’ll need a good close focusing distance on your binoculars. The Nikon Sportstar EX 10×25 has a close focusing distance of 3.5m and is equipped with a twist-type diopter ring for manual focus adjustment for each eye.

The Verdict

Because of its premium performance, stability and good magnification, we give it an overall rating of 4.5 (out of 5). Also, versatility is the keyword for this model.

All in all, the Nikon Sportstar EX 10×25 is an option worth considering if you are looking for comfortable, waterproof and durable binoculars for water sports, but more broadly for daily indoor and outdoor use “outside”.

This pair of binoculars offers both a wide field of view and close focus. We appreciate these binoculars among other things for their compactness and lightweight design, which make you forget that they are around your neck.
