Z series
The Z series contains the top products in the PENTAX Sport Optics range. This series consists exclusively of roof prisms in premium quality, which will catch the eye of even the most critical observer. All binoculars in this series are manufactured in Japan.
In addition to ED lenses, the ED series has an additional dielectric coating. This raises the color brilliance and color fidelity to an extraordinary level and inspires the most demanding users and dedicated observers.
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. The "Full-Multi-Coating" of all lenses is the new standard coating. It improves light transmission and contrast while minimizing reflections and ensuring excellent colour 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 colour rendition.
Protective lens coating
The lenses in the Z series are specially coated with the "Protective Lens Coating". Based on nanotechnology, this water, oil, dust and dirt-repellent hydrophobic protective coating on the outer optical elements prolongs visual comfort in the long term. The corresponding PENTAX binoculars therefore impress even under the toughest viewing conditions. In addition, the ED series in the Z series has a dielectric coating, which increases the color brilliance and color fidelity to a considerable level.
BaK4 glass prisms
As the light rays in a prism are deflected several times at different angles, the composition of the optical glass is of crucial importance. PENTAX binoculars therefore only use prisms made of high-purity BaK4 glass with a high refractive index.
Phase correction
The design of roof prisms poses a particular 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.
Waterproof
In keeping with the motto "Always with you.", PENTAX Sport Optics binoculars are also subject to special requirements. All binoculars with the additional designation "WP" are waterproof in accordance with JIS class 6 and can therefore withstand accidental immersion in water up to 1 m deep.
Internal focusing
Internal focusing protects the binoculars from the ingress of dust, foreign bodies and moisture. This ensures functionality over a long period of use.
Aspherical lens elements
These specially manufactured lenses reduce imaging errors to a minimum and are responsible for sharp and brilliant image reproduction right up to the edges. The aspherical hybrid lenses of the Z series not only provide outstanding imaging performance, they also enable a compact and lightweight design.
ED lenses for natural color rendition
Top-quality lenses must be free of disturbing color errors (chromatic aberration). Special ED front lenses with low dispersion are used in the Z-series lenses for this purpose. These special lenses enable a lighter and more compact design, in contrast to apochromatic lens systems.
Dielectric coating
A dielectric coating on the prisms maximizes color fastness. Up to 70 layers of color correction coating are vapor-deposited onto the prisms.
Nitrogen filling
All binoculars in the Z-series are nitrogen-filled to prevent condensation in the binoculars as well as the ingress of dust and tiny airborne particles.
Lightweight magnesium alloy body
The magnesium alloy body makes the binoculars not only particularly stable but also very light. The complete coating with rubber armoring provides additional protection against pressure and impact.
Long eye point
The long eye point of PENTAX binoculars makes them very comfortable to use.
Spectacle wearers in particular will appreciate being able to see the full field of view.
Quality for years to come
RICOH IMAGING offers a 30-year warranty on PENTAX Sport Optics products to ensure that all binoculars remain a pleasure to use.
