Alike the entire Genesis series, the Kowa Genesis 8.5x44 DCF ED Binoculars are waterproof, fog-proof and nitrogen filled. This enables you to enjoy your viewing experience without the fear of breakage or a lacklustre performance. The binoculars also feature a lightweight magnesium alloy body and durable rubber armour so you can use them for long periods at a time without tiring yourself. Furthermore, these binoculars come with a 10 year warranty so these binoculars will undoubtedly be your favourite travelling companion for years to come.
Needless to say, the Kowa Genesis 8.5x44 DCF Binoculars reinforce the world renown of Japanese optical engineering.
The "PROMINAR" XD Lenses combined with a concave lens possessing special dispersion properties dramatically reduces the possibility of chromatic aberration. This ensures that discolouration, graininess or blurriness is an issue of the past! The lens are also coated with C3 coating which is build to enhance the prism reflection rate. Ultimately this technology optimises the amount of light gathered so that you attain a brighter and clearer field of view.
All lenses have multilayer coating so you that you attain a wider field of view
One of the major causes of deterioration of viewing quality in optics is chromatic aberration (colour blur). Chromatic aberration occurs due to the dispersion of light and the different wavelengths of light focusing on different positions, resulting in a red or purple fringing around the image. The optimum optical material to minimise chromatic aberration is fluorite crystal.
A fluorite crystal with extremely low dispersion characteristics is used for the convex lens of the KWA-8544/KWA10544 PROMINAR models. In place of an ordinary optical glass lens, the concave lens paired with the fluorite crystal lens is made of glass with special dispersion properties to reduce the chromatic aberration to a further degree.
This combination of fluorite crystal and glass with special dispersion properties nearly eliminates chromatic aberration and redefines the standards of colour brilliance.
This technology is the result of many years of optical design and has realised great reduction in chromatic aberration, while maintaining a large diameter lens and high contrast images when compared with conventional models.
The XD lens used in the KWA-G8544/KWA10544 PROMINAR models has characteristics similar to those of fluorite crystal to significantly reduce the chromatic aberration. All lenses are environmentally friendly Eco-Glass. (Eco-Glass is an environmentally friendly glass that does not contain lead or other harmful substances.)
