Kowa BD III-XD 10x50

The Kowa BD III-XD 10×50 is a full-size roof-prism binocular designed for detailed outdoor observation. It combines 10x magnification with 50mm objective lenses, providing a 5mm exit pupil and a 6.6° real field of view. As part of Kowa’s BD III-XD series, this model features XD extra-low dispersion optical elements designed to reduce chromatic aberration and support clear, high-contrast viewing. Its optical configuration is suitable for observing distant subjects across open landscapes and natural environments.

The binoculars provide a field of view of 346 feet at 1,000 yards, allowing users to scan broad areas while observing birds, wildlife, and other distant subjects. A 17mm eye relief supports comfortable viewing, while the 9.8-foot minimum focusing distance provides flexibility when observing subjects at relatively close range. The interpupillary distance can be adjusted between 57 and 76mm to accommodate different users.

The Kowa BD III-XD 10×50 features a magnesium alloy body with protective rubber armoring, combining structural durability with a secure grip. Its waterproof, nitrogen-filled construction helps protect the internal optical components against moisture and internal fogging in changing outdoor conditions. Weighing approximately 25.5 ounces, this model is designed for users who prioritize 10x magnification, large objective lenses, and dependable optical performance for birdwatching, wildlife observation, and outdoor exploration.
