Pentax Binoculars SD 8x42 WP (49526)

Pentax SD 8x42 WP binoculars belong to the S-series, which includes both roof and porro prism models with objective lenses larger than 40mm. These binoculars are designed for users who want bright, high-contrast viewing in a variety of outdoor environments. The S-series features advanced light transmission coatings, and waterproof porro prism models also have a hydrophobic coating for clear, contrast-rich images even in challenging weather conditions.

Optical Performance:
Fully multi-coated lenses are used to maximize light transmission and reduce flare and ghosting. Multiple layers of coatings are applied to every lens and prism surface, resulting in clear and crisp images. Enhanced light transmission coatings, using advanced film-deposition technology, further improve brightness and color accuracy.

Durability:
A protective nano-coating is applied to the exterior lens surfaces to repel water, oil, dust, and dirt. This makes the binoculars easy to maintain and suitable for harsh outdoor conditions.

Key Features of the SD-Series:

• BaK4 prisms offer a high refractive index for a perfectly round exit pupil and clear, unvignetted images.

• Phase correction coating on roof prisms improves image sharpness and color fidelity.

• Waterproof construction is fully sealed and nitrogen-purged, providing fogproof performance and allowing submersion up to 1 meter (JIS Class 6 rating).

• Nitrogen purging prevents condensation and keeps dust and particles out of the housing.

• Inner focus optics design protects internal components from airborne particles and moisture, ensuring long-term reliability.

• Long eye relief design makes viewing comfortable for eyeglass wearers and reduces eye strain during extended use.

• Accessories include objective and eyepiece caps, a case, and a strap.
