Kowa BD II 10x32 XD Binoculars — Affordable, High-Definition Optics for Birding

The BD II 10x32 XD marks the third generation in Kowa’s BD lineup, built for birders who refuse to compromise on image quality. At the heart of these binoculars are XD (ED) lenses that incorporate fluorite crystal, delivering unmatched light transmission, edge-to-edge sharpness, and zero chromatic aberration. The result is a bright, high-contrast scene with natural color accuracy—from distant warblers to fleeting butterflies.

What makes them stand out

• XD fluorite glass: exceptional resolution and color fidelity, with minimal halo or color fringing across the field of view.
• Wide, practical field of view: 6.7° (351 ft / 117 m at 1000 yd / 1000 m), making it easier to track birds in motion and scan complex habitats.
• Close focus to 1.3 m: ideal for observing small subjects up close, from insects to leaf textures and flower centers.
• Lightweight yet rugged: magnesium alloy chassis combined with a durable rubber armor for comfortable, all-day use in varying weather.
• Nitrogen-filled and fully waterproof: dependable performance in rain, fog, and humidity with reduced internal fogging.
• Coatings tuned for clarity: phase-coated prisms, fully multi-coated lenses, C3 coatings on prisms, and KR coatings on lenses to resist dirt and enhance contrast.
• Ergonomic design: soft twist-up eyecups, 15 mm eye relief for eyeglass wearers, and a positive, glove-friendly focus wheel for precise adjustments on the move.
• Tripod adaptable: stability for extended viewing sessions or perched observations without hand fatigue.
