in Stock

Series "A"

The "A" series consists of roof and porro prism models with objective < 40mm lenses.

Thanks to new fully multi-coated lenses, phase correction, Bak4 prisms and a new coating for enhanced light transmission, these binoculars provide crystal clear images and excellent contrast. They have all the quality features one can find throughout PENTAX's roof prism range: fully coated lenses, internal focus, waterproofing, dust resistance, nitrogen filling, rubber casing, wheel focus, twist-up eyepieces for comfort of use and ease of focus. Thanks to its modern design, small and compact size and high performance features, the "A" series provides unsurpassed visual enjoyment.

New optical parts, fully coated with multiple coating.

With this new technology, the amount of light that penetrates the lenses is maximized, preventing flare and ghosting so that they do not interfere with your visibility. PENTAX places this multi-layer coating on all surfaces of each element of lenses and saws throughout the Range of Sport Optics. This ensures the maximum light transmission that results in a clear image.

New coating for enhanced light transmission

Pentax binoculars take the quality of optical parts to the next level, placing an improved technology film on the surfaces of lenses and saws. This results in increased light transmission and bright images are created with accurate color rendering.

BaK4 Prisms

Thanks to its excellent refractive index, the prism's Bak4 glass, found in all the binoculars of PENTAX's Sport Optics class, is known for its round output aperture and clear images.

Phase correction

The intricate design of the optical parts in roof prism binoculars provides durable, compact and at the same time lightweight construction. But it requires a higher level of visual perfection. PENTAX places a phase correction coating throughout the range of "roof prism" cells to maximize viewing quality.

PENTAX Waterproofing

PENTAX waterproof products are fully waterproof and "paid" with, laboratory quality, nitrogen to provide perfect viewing with anti-dazzling effect even in the most adverse conditions. Class 6 JIS waterproofing guarantees up to 1 meter deep immersion.

Internal focus system

The refined design of the optical parts is crucial for the low maintenance costs and long life of PENTAX's cells. Exposure to suspended particles and moisture is avoided, thus ensuring that there are no external influences that can penetrate the housing and disrupt functionality.

Nitrogen filling

Nitrogen is a chemical element and a colorless, odorless and tasteless gas. It has a very low moisture content and is used in the manufacture of cells and telescopes. Due to the low humidity index, nitrogen prevents the creation of blur in the internal lenses of the optical organs in phases where the temperature changes abruptly. In addition, because the organs are "filled" with nitrogen, they are at a slightly higher atmospheric pressure, causing dust and other microscopic particles to be prevented from entering their enclosure.

"Long eye relief" design technology

The "long eye relief" technology found throughout PENTAX's Range of Sport Optics allows the user to see the entire field clearly and effortlessly. This is extremely beneficial to users who wear eyeglasses allowing extensive use without straining the eyes.
