Pentax SP 20x60 WP

S Series

The S-Series roof prism and porro prism binoculars feature objective lens diameters greater than 40 mm. Equipped with the same high-quality coatings of the A series, impeccable image quality is guaranteed. Characteristic of this series is the high light-gathering power due to the large objective lens diameter.

Multiple coatings on all lenses

Optimum light transmission is one of the most important aspects for the visual quality of binoculars. This is also the focus of the new technologies for the current PENTAX Sport Optics series. For example, the "Full Multi-Coating" of all lenses is considered the new standard coating. It improves light transmission and contrasts while minimizing reflections and providing excellent color fidelity.

Enhanced Light Transmission Coating

The new "Enhanced Light Transmission Coating" raises the optical level of the new PENTAX binoculars to a significantly higher level. This optimized light transmission coating increases light transmission and guarantees exceptionally bright images with precise color reproduction.

BaK4 glass prisms

Since the light rays in a prism are deflected several times at different angles, the quality of the optical glass is of decisive importance. For this reason, only prisms made of high-purity BaK4 glass with a high refractive index are used for PENTAX binoculars.

Phase correction

The design of roof prisms presents a special challenge. Here, the light rays are reflected several times, resulting in a shift of the light waves. An additional phase correction coating on all PENTAX roof prisms corrects the frequency of the light rays back to the natural value.

Waterproofing
In keeping with the motto "Always with you." the binoculars from PENTAX Sport Optics are also subject to special demands. All binoculars with the additional designation "WP" are waterproof according to JIS class 6 and can therefore withstand accidental immersion in water up to 1 m deep.

Nitrogen filling

All binoculars in the S series are nitrogen-filled to prevent condensation in the binoculars as well as the ingress of dust and minute airborne particles.

Internal focusing

Internal focusing protects the binoculars from penetration by dust, foreign bodies and moisture. This ensures functionality over a long period of use.

Long eye point

The long eye point on PENTAX binoculars allows very comfortable use. Spectacle wearers in particular will appreciate being able to grasp the full field of view.
