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

The well-positioned controls, including the central focus wheel, contribute to the overall ease of use, allowing for quick and effortless adjustments.

Optical Performance and Possible Uses
Nikon Sportstar EX is equipped with 25mm objective lenses, featuring excellent quality roof prisms and multi-coated lenses. This design maximizes light capture and utilization and enhances the overall optical performance. 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.
It has 10x magnification, making 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. This device has 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 binocular has a close focusing distance of 3.5m and is equipped with a twist-type diopter ring for manual focus adjustment for each eye.
However, one potential limitation of this model is its reduced low-light performance, attributed to the smaller objective lens size of 25mm. Smaller objective lenses capture less light, which can impact image brightness, particularly in low-light conditions.
In summary, the Nikon Sportstar EX 10×25 could be a good option for those looking for comfortable, waterproof, and durable binoculars suitable for water sports, as well as everyday indoor and outdoor activities. With its premium performance, stability, and commendable magnification, it earns an overall rating of 4.5 out of 5. The versatility of this model makes it a well-rounded choice for a range of observational needs.
This pair of binoculars offers both a wide field of view and close focus. With compact and lightweight design their unobtrusive nature allows users to almost forget they are hanging around their necks.
