Kowa BD II 8x42 XD Binoculars

The Kowa BD II 8x42 XD Binoculars (product 47032170643763) deliver 8x magnification through a 42mm objective lens. That pairing gives you a bright 5.25mm exit pupil and a class-leading 8.2-degree field of view 143m at 1000m. That wide angle makes tracking birds and moving wildlife significantly easier. Close focus sits at just 1.8m which is genuinely useful for watching insects or nearby subjects.

The optical core uses Kowa XD high-grade ED glass with fluorite crystal construction to eliminate colour fringing. ED extra-low dispersion glass produces sharp images with natural colour across all light conditions. Kowa's KR coating on the external optics actively resists dirt and residue build-up keeping the view clean in the field.

The body is magnesium alloy wrapped in rubber armour. It weighs just 640g making it comfortable to carry all day. Fully waterproof and dry nitrogen filled so fogging is not a concern. Twist-up eyecups suit glasses wearers and the aluminium focus wheel is fast and precise. Dimensions are 139x128x52.5mm.

A 10-year manufacturer warranty backs the build quality. For birdwatching and wildlife use this is a well-specified 8x42 that punches above its price point with genuine optical performance.

The 8x42 format means 8x magnification through a 42mm objective lens giving a 5.25mm exit pupil enough light for dawn and dusk use. Kowa's XD ED glass uses fluorite crystal to reduce chromatic aberration so colours stay true and edges stay sharp. The roof prism design keeps the body compact. KR coating on the outer lenses repels dirt. The 8.2-degree field of view is class-leading for this format and the nitrogen fill prevents fogging when temperatures change.

The chassis is magnesium alloy strong and light at 640g. A rubber armour layer covers the exterior for grip and impact resistance. The lenses use Kowa XD high-grade ED glass with fluorite crystal construction. External optics carry KR coating to resist dirt and residue.

Clean lenses with a blower then a microfibre cloth only. Store in the case when not in use and keep the strap attached. Keep the body dry and check the eyecups twist smoothly. The 10-year warranty requires normal careful use avoid dropping or immersing beyond the waterproof rating.
