High quality wide angle optics for bird watching and nature observation. These binoculars combine eyepieces for eyeglass wearers with a wide-angle field of view in a handy design. They are ideal for nature observation in any weather. The sharp, high-contrast, and true-color image is achieved through multi-coating and BaK-4 prisms. The Porro binocular geometry provides a particularly vivid image, even in low light conditions. Nitrogen filling prevents fogging of the inner optics, even at large altitude and temperature differences. The large, easy-grip central focus and very easy-to-grip diopter adjustment allow for easy operation, even with gloves.
