The Kowa Genesis Binoculars are specially designed to offer outstanding performance and impressive viewing quality. Combining Kowa's own Prominar ED glass for minimising chromatic aberration with a C3 optical multi-coating that offers 99% or more reflectivity across the entire visible spectrum (400 nm to 700 nm), these binoculars are perfect for terrestrial observation, especially fauna and birds. The optical qualities allow you to use them even in low light environments or with reflections, such as for watching water birds at sunset. Plus, they showcase an extremely rugged lightweight magnesium frame that is the foundation of the fog-proof and waterproof body. The reliability and durability of these binoculars allow you to use them confidently, even in severe situations. The internal focusing helps to keep the overall operating size from becoming unwieldy and the prism system provides an edge-to-edge sharpness and wide field of view with minimal loss of light.
