Fujinon KF 10x42 W Details

A good all-round instrument, these 10x42 Fujinon KF binoculars are ideally suited to outdoor enthusiasts and especially hunters or nature observers who mostly operate in reasonably good light, in wide open spaces and at medium to longer ranges.
The 10x magnification presents the user with a good level or reach and in combination with the first-class optical glass and coatings, a high degree of detail and definition. The compromise is that compare to most 8x42 binoculars, these have a narrower field of view.
42mm objective lenses are a popular option as they are capable of capturing a good amount of light, but are not so big as to make the binocular to difficult to carry. This in combination with their open bridge body design makes them secure to hold onto in the field and a comfortable binocular to have around your neck all day long.
At 2.5m away, the close focus distance on these is good for a 10x42 binocular and so will please those nature lovers who like to study butterflies, other insects or even flowers from close range.
In combination with the twist-up eyecups, the 15mm of eye relief should be sufficient for all users, except for those who need to wear glasses whilst using their binoculars.

Description of Fujinon KF Binoculars

KF Fujinon binoculars offer pocket, compact and all-round models suitable for different nature observations of huntersbirdwatcher, hikers and are also perfect for military and law-enforcement applications. These KF series made in Japan has a roof prism design that makes them incredibly compact and comfortable to handle with the help of open-bridge design. Good protection and multi-coated lenses together with high-quality optical technology that offers crystal clear images make them no doubt one of the best in the market. 

Basic Feature

These incredibly versatile binoculars have great ergonomics due to open-bridge design. This allows you to grab them more firmly with a wrap-around grip by the help of rugged armoring. This stylish rubber that comes in greyish hue is designed together with a straight-through design that makes them incredibly compact. Very durable aluminum body makes them impervious together with tight seals, so the construction is fully waterproof. They are also filled with nitrogen gas to prevent internal fogging to occur inside them, so your clear-viewing will never be compromised. Their robust and thick rubber armoring also makes them shock-proof and protects them against impact, abrasions and against temperature extremes. Therefore, they are able to withstand the most severe weather, not only rain and snow, but also hurricanes or desert heat. These binoculars are equipped with grippy central focusing wheel that is very smooth, together with right-eye diopter that helps you eliminate differences in both eyes. Individual focusing is only integrated into smallest pocket 7x28H model. Eyecups aren’t foldable as in most of Porro prism binoculars, but are multi-positioned and softly tethered so they feel incredibly comfortable when pressed against the face.
