Pentax Binoculars SP 20x60 WP (49535)

Pentax SP 20x60 WP binoculars are part of the S-series, which features both roof and porro prism models with objective lenses larger than 40mm. This series is designed for users who require bright, high-contrast viewing in demanding outdoor conditions. The waterproof porro prism models include a hydrophobic coating, ensuring clear images even in wet or humid environments.

Optical Performance:
These binoculars offer 20x magnification and have large 60mm objective lenses. Fully multi-coated optics are used, with multiple layers of coatings on every lens and prism surface. This maximizes light transmission, reduces flare and ghosting, and delivers bright, crisp images with accurate color. BaK4 prisms provide a high refractive index, resulting in a perfectly round exit pupil and a clear, unvignetted image. Enhanced light transmission coatings further improve brightness and clarity, even in low-light conditions.

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, and the surface provides a secure, slip-resistant grip. The body is nitrogen-filled and O-ring sealed, making the binoculars waterproof and fogproof. They are submersible up to 1 meter (JIS Class 6 rating).

Comfort and Handling:
Long eye relief (21 mm) makes these binoculars comfortable for eyeglass wearers. Rotatable eyecups allow for easy adjustment and help block stray light. The central focusing system is smooth and precise, and a threaded tripod connector is included for stable, hands-free use. Due to the high magnification and weight, tripod use is recommended for extended observation.

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