Thanks to the 10x magnification , the Leica Noctuid 10x42 offers the best detail rendition. The excellent stray light suppression and high contrasts the finest detail resolution even under the most difficult light conditions. The short close focus range ensures richly detailed images just like in a large format, and the generous field of view provides a wide overview at greater distances. The compact dimensions and the perfect balance ensure a fatigue-free and relaxed viewing experience. A non-slip rubber armoring gives the binoculars a comfortable feel, and the highly durable patented special varnish provides additional protection for the metal surfaces of the robust magnesium housing.
