Pentax Binoculars SP 10x50 WP (49533)

Pentax SP 10x50 WP binoculars are part of the S-series, which offers both roof and porro prism models with objective lenses larger than 40mm. These binoculars are designed for users who need bright, contrast-rich viewing in demanding outdoor conditions. The waterproof porro prism models feature a hydrophobic coating, ensuring clear and bright images even in rain or fog.

Optical Performance:
Fully multi-coated lenses are used throughout the optical system, with multiple layers of coatings on every lens and prism surface. This maximizes light transmission, reduces flare and ghosting, and delivers clear, crisp images with accurate color. BaK4 prisms provide a high refractive index for a perfectly round exit pupil and a bright, unvignetted view.

Durability and Protection:
A nano-technology protective coating on the exterior lens surfaces helps repel water, oil, dust, and dirt. The binoculars are covered with rubber armoring for excellent resistance to shocks and impacts. They are nitrogen-filled and O-ring sealed, making them waterproof and fogproof, and can be submerged in up to one meter of water (JIS Class 6 rating).

Comfort and Handling:
Long eye relief (20 mm) makes these binoculars comfortable for eyeglass wearers. The rotatable eyecups allow for easy adjustment. The central focusing system is smooth and precise, and a threaded tripod connector is included for stable, hands-free use. The traditional porro prism design offers a wide field of view and comfortable grip.

Included Accessories:
A soft carrying case, neck strap, objective lens caps, and eyepiece caps are included.
