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.
This binocular was created for heavy duty applications. The rubber armoured waterproof and nitrogen-purged body withstands
weather, dust or rough impact. Add high imaging capability and you have a binocular that will accompany you to the extremes, on
land or on water! Includes a powerful 20 x 60 for long-range or astronomy observations.
Main Features
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 lineup. These fully-multi-coated optics assure the maximum light transmission
resulting in a clear, crisp view of the world.
Aspherical lens elements
Edge-to-edge sharpness is a vital element to comfortable viewing. To
achieve this, we utilise aspherical lens elements in our eyepieces. This is a
specially shaped lens design that reduces aberration to a minimum.
Nitrogen purged
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.
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.
BaK4 prisms
Long eye relief design
Protective Lens Coating
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 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.
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.
Superb impact resistance
PENTAX Waterproofing
Other Features
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.
Unique Hydrophobic Coating
Water droplets on a lens have a negative influence on the ability of light to
enter the objective lens. By using a unique water repellent coating on all
outer lenses we make water drops “bead” into small, deformed droplets.
The deformed droplets cause less distortion and “slide” more easily off
the lens. Your binocular remains fully functional even in rain, snow, fog or
condensing breath.
The body is made from magnesium, which adds toughness while keeping
the binoculars light. In addition, the exterior rubber coating provides the
binoculars with superb resistance to shocks and impacts.
Helicoid three-stop eyepiece rings that permit fine adjustment for
maximum viewing comfort
