— High class binoculars
with a lightweight design
and outstanding maneuverability
HOYA CORPORATION PENTAX Products is pleased to announce the PENTAX 9×28 DCF LV binoculars, high-class roof-prism binoculars that realize outstanding maneuverability through a lightweight design, and an advanced optical system which offers a bright and clear field of view, as well as high waterproofing/impact-resistant properties.
Bright and clear field of view
For the 9×28 DCF LV, multi-coating is applied on all lenses surface as well as the permeable surface of the prism to significantly improve the light transmission. In addition, phase correction coating, to increase the resolution and contrast, and high-reflection coating, to increase reflectivity, are applied to the reflecting surface of the prism. A bright and clear field of view even of peripheral areas is obtained through this prism that uses 3 types of coatings and high-refraction glass BaK4.Lightweight design
The 9×28 DCF LV uses reinforced plastic for its main body material, realizing the lightweight binoculars while securing high rigidity. Outstanding maneuverability is also achieved through a compact design with 28mm objective lens.Waterproofing capability
The 9×28 DCF LV is equipped with waterproofing capabilities* (JIS Class 6 equivalent, water resistant to a depth of 1m (3.3 feet) ) that can be used in wet conditions, and can be rinsed in water when they get dirty. In addition, filling nitrogen gas inside the main unit, which is fully-sealed, prevents the inner surface of the lens from becoming fogged due to differences in temperature.*The 9x28 DCF LV cannot be used in underwater.
Full rubber coating
In addition to improving the grip by using full rubber coating on the exterior, the 9×28 DCF LV realizes great impact resistance.Other features
