Kowa BD III 8x42 XD Binoculars (Kowa, SKU: 138461 / 12801) are wide-angle roof prism binoculars designed for birdwatching, wildlife and landscape observation, travel, and versatile outdoor use. The 8× magnification combined with 42 mm objective lenses provides a large 5.3 mm exit pupil, while the exceptionally wide 8.2° field of view makes it easier to locate and follow moving subjects. Kowa XD lenses made from extra-low dispersion ED glass reduce chromatic aberration, while the lightweight magnesium alloy body, waterproof nitrogen-filled construction, and protective KR coating prepare the binoculars for regular use in the field.
