Product Features in Detail

Dual-axis eye-distance adjustment system
As a binoculars user, the dual-axis eye-distance adjustment system will help ensure optimum alignment for viewing.

Fully multi-coated optical elements
The main advantage of fully multi-coated optical elements is the elimination of harmful ultraviolet rays and glaring. With this feature, you'll only see the necessary view and none of the side-effects of outdoor binocular viewing.

Rubber Housing
Holding on to your binoculars is made easier with a rubber housing that also functions as protection for its internal mechanisms.

PENTAX PentaBright Technology: Your Best Solution for Top-Quality Viewing
The complex science of optics requires attention to the type and quality of glass, design, construction, eye relief, tube alignment, sealing against moisture, and user comfort. PENTAX has been an innovator in the field of optics for over 90 years, so no one knows optics better than PENTAX. We pioneered multi-layer lens coatings which greatly increase light transmission efficiency that delivers bright, high contrast images without flare. This establishes the core of our PentaBright technology.

Super-Multi-Layer Coating
All optical elements within every PENTAX product are treated with our time-proven multi-layer coating which not only improves light transmission to deliver bright, high contrast images without flare, but also reduces eye fatigue even during extended observation.

Durable Construction
Every PENTAX Sport Optics instrument is built to the highest of standards using some of the toughest materials available. PENTAX binoculars and spotting scopes are encased in highly durable rubber-armored housings, which are designed to protect the optical mechanisms inside from shock and damage, while making them easier to hold. PENTAX waterproof products are fully sealed and feature airtight construction. They are purged with laboratory grade nitrogen to provide a fog proof view in the harshest weather conditions, and extreme temperatures.* *Not designed for underwater use.

Long Eye Relief
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.

High-Refraction BaK4 Glass Prism
Due to its outstanding refraction index, the BaK4 glass prism is highly acclaimed for its perfectly round exit pupil and clear, unvignetted image.

Aspherical Optical Elements
The PENTAX aspherical optical elements greatly improve image brightness and sharpness, while minimizing disturbing distortions.

High-Resolution Phase Coating
The roof prisms of all DCF series models are specially treated with high-resolution phase coating. Previously incorporated only in the most expensive models, this special process cancels the phase difference created on the wave front of light passing through a roof prism, thus producing sharp, high-contrast images with much improved resolution.

Inner-Focus Optical Design
Incorporated in all DCF series models, plus the UCF and PCF WP II models, this sophisticated optical design is ideal for waterproof models that require a fully airtight body construction. It also contributes to a considerable reduction in size and weight and improves overall balance by minimizing weight shift during focusing.

Functional, Maneuverable Body Design
The body and optical mechanism of PENTAX binoculars and spotting scopes are computer-designed to ensure the easiest handling possible and minimize overall size and weight, without sacrificing optical performance.
