Pentax Binoculars SP 16x50 (49531)

Pentax SP 16x50 binoculars are part of the S-series, which includes both roof and porro prism models with objective lenses larger than 40mm. This series is designed for users who need bright, high-contrast viewing in a range of outdoor conditions. The waterproof porro prism models feature a hydrophobic coating, helping to maintain clear images even in challenging weather.

Optical Performance:
These binoculars are equipped with fully multi-coated lenses, with multiple layers of coatings applied to every lens and prism surface. This maximizes light transmission, reduces flare and ghosting, and ensures clear, crisp images with accurate color. Enhanced light transmission coatings further improve brightness and color fidelity. BaK4 prisms are used for their high refractive index, resulting in a perfectly round exit pupil and a bright, unvignetted image.

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. These binoculars are splash-proof but not fully waterproof.

Comfort and Handling:
Fold-down eyecups and 13 mm eye relief make them suitable for eyeglass wearers. The central focusing system is smooth and precise, and a threaded tripod connector is included for stable, hands-free use. The classic porro prism design offers a wide field of view and comfortable handling, though the high magnification makes tripod use recommended for extended observation.

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