PENTAX AD-Series
The AD-series consists of roof 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.

Features A-Series

• 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 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 color 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.
• Phase Correction
  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.
• Waterproofing
  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.
• Nitrogen purged
  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.
• Inner Focus Optics Design
  This sophisticated optical design is critical to low-maintenance and long life guarantee. Exposure to airbourne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the housing and disrupt functionality.
• Long eye relief design
  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.
