Pentax Binoculars SP 8x40 (49528)

Pentax S-series binoculars are available in both roof and porro prism designs, all featuring objective lenses larger than 40mm. This range allows users to choose according to their personal preferences. The S-series is equipped with advanced light transmission coatings, and the waterproof porro prism models include a hydrophobic coating, delivering bright, high-contrast views even in challenging outdoor conditions.

Fully multi-coated optics
All lenses and prisms are treated with multiple layers of coatings to maximize light transmission. This reduces flare and ghosting, ensuring a clear and crisp image. The result is bright, true-to-life viewing in various lighting situations.

Enhanced light transmission coatings
A new film-deposition technology is used on lens and prism surfaces to further boost light transmission, producing brighter images with accurate color reproduction.

Protective lens coating
To increase durability, a nano-technology coating is applied to the exterior lens surfaces. This coating repels water, oil, dust, and dirt, helping the binoculars withstand harsh conditions.

SP-Series Features
BaK4 prisms are used for their excellent refractive index, creating a perfectly round exit pupil and a clear, unvignetted image. The exterior rubber coating gives the binoculars outstanding resistance to shocks and impacts, while also providing a secure grip.
