Pentax Binoculars SP 10x50 (49529)

Pentax SP 10x50 binoculars are part of the S-series, which offers both roof and porro prism models with objective lenses larger than 40mm. This series is designed for users who need bright, contrast-rich viewing in a variety of outdoor situations. The S-series features advanced light transmission coatings, and waterproof porro prism models also include a hydrophobic coating for clear and vivid images even in challenging weather.

Optical Performance:
These binoculars feature fully multi-coated lenses, with multiple layers of coatings on every lens and prism surface. This maximizes light transmission, reduces flare and ghosting, and ensures clear, crisp images with accurate color. BaK4 prisms are used for their high refractive index, providing a perfectly round exit pupil and a clear, 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. The binoculars are splash-proof but not fully waterproof.

Comfort and Handling:
These binoculars have a 13 mm eye relief, making them comfortable for eyeglass wearers. Folding 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 classic porro prism design offers a wide field of view and comfortable handling.

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