Description
The Pentax AD 9×28 WP Binocular is a full-size performer in a semi-compact body, offering fully multi-coated optics, enhanced light transmission coatings, and a fully waterproof exterior. It has been designed with a Super Reflective Prism coating, including a phase correction coating, and a rubber-covered body provides protection and grip.
The A-series consists of roof and porro prism models with objective lenses < 40mm. Offering impeccable viewing quality through the application of the same advanced coatings, this series is considered the compact, portable and durable smaller brother of the S-series. Users can enjoy a mobility convenience without compromising optical performance.
Thanks to new fully multi coated lenses, phase correction, BaK4 prism, and new enhanced light transmission coating, these binoculars provide crystal sharp images and superb contrast. They have all the quality features found in the entire roof prism range PENTAX has on offer: inner focusing, water and dust proof, nitrogen-purged, fully rubberized body, focus wheel and twist-up eyecups for comfortable handling and easy focusing. Thanks to modern design, compactness and high performance features, they deliver outstanding viewing enjoyment.
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 line-up. These fully-multi-coated optics assure the maximum light transmission resulting in a clear, crisp view of the world.
New Enhanced Light Transmission Coatings
PENTAX binoculars take quality optics to the next level by applying a new, optimized film-deposition technology on lens and prism surfaces resulting in increased light transmission which creates bright images with accurate colour rendition
BaK4 Prisms
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.
