    HIGHLY RESPECTED STANDARD, GETS A NEW DESIGN
    S-series
    The S-series consists of both roof and porro prism models with objective lenses > 40mm so personal preferences are immediately defined. In addition to the newly developed light transmission coatings, waterproof porrro prism models also boast the hydrophobic coating, thereby allowing for contrast-rich, bright viewing under rough outdoor conditions.
    These binoculars meet the viewer’s traditional demand for 8x magnification. It has all the quality features found in the entire roof prism range PENTAX has on offer: fully multi-coated lenses, inner focusing, water and dust proof, nitrogen-purged and phase correction coatings on the BaK4 prisms. The new Enhanced light transmission coating creates crystal sharp images. The polycarbonate housing makes the whole package a full-size light-weight. It also offers 4-stop, helicoid eyecups. When weight is a critical factor for you, then these binoculars are the perfect reason to upgrade to full size.
    New Fully-multi-coated optics
    Fully multi-coated lenses serve the essential purpose of maximizing the amount of light passing through a lens, thereby prevent flare and ghosting from interfering with your view. PENTAX applies multiple layers of coatings to every surface of every element and prism in the full Sport Optics line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.
    New Enhanced Light Transmission Coatings
    PENTAX binoculars take quality optics to the next level by applying a new, optimized film-deposition technology on lens and prism surfaces resulting in increased light transmission which creates bright images with accurate color rendition
    Protective Lens Coating
    All optical surfaces are delicate and must be handled with care to prevent scratching. To add to the durability of the Z- and S-series Water Proof binoculars*, PENTAX has added a protective, nano technology coating that helps deflect water, oil, dust and dirt. This allows PENTAX binoculars to withstand the harshest viewing conditions.
    BaK4 prisms
    Due to its outstanding refractive index, the BaK4 glass prism found in all PENTAX Sport Optics is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.
    Phase Correction
    The complex optical design of roof prism binoculars provide durable, compact, yet lightweight design but require a higher level of optical perfection. A phase-correction coating is applied in the full range of roof prism binoculars to maximize image viewing quality.
    PENTAX Waterproofing
    PENTAX waterproof products are fully sealed and purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions. With a JIS Class 6 rating, PENTAX waterproof binoculars can even be submerged in up to 3 feet of water.
    Inner Focus Optics Design
    This sophisticated optical design is critical to low-maintenance and long life guarantee. Exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.
    Nitrogen purged
    Nitrogen is a chemical element and a colorless, odorless and tasteless gas. It contains very little humidity and is therefore used to “purge” binoculars and spotting scopes of the high humidity air that is part of our environment. Due to the low humidity factor, nitrogen prevents condensation from forming on the internal lenses of optical instruments during phases of rapid temperature change. Furthermore, because nitrogen is purged into the optical instrument at slightly above atmospheric pressure, dust and other miniscule particles are prevented from entering the housing.
    Long eye relief design
    The long eye relief offered in all PENTAX Sport Optics allows the viewer to see the entire field of view clearly and effortlessly. This is especially beneficial to eyeglass wearers, and allows viewing for extended periods of time without added eye strain.
    Other Features
    Helicoid three-stop eyepiece rings that permit fi ne adjustment for maximum viewing comfort.
    Exterior rubber coating that provides the binoculars with superb resistance to shocks and impacts.
