Pentax

Pentax's 9x28 A-Series AD WP Binoculars feature an exciting transitional magnification that produces an enhanced viewing experience over a lower power without the visible hand-shake often associated with higher magnifications. The BAK4 roof prisms are phase-corrected to improve image contrast and enhance color rendition. All of the optics are anti-reflection fully multicoated to maximize light transmission to produce the brightest views possible.To help cut weight, the housing is made of corrosion and impact-resistant fiberglass reinforced polycarbonate polymer. They are also temperature-resistant allowing for their use in extreme climates while reducing expansion and contraction wide temperature swings can cause which can make the optical components move out of collimation over time. Their optical tubes are nitrogen-filled and O-ring sealed so they can are submersible to 3.3', as well as fogproof in all weather conditions.Optical Performance 9x magnification28mm objective lensesBAK4 roof prismsPhase corrected prism coatings enhance contrast and improve color renditionAnti-reflection fully multicoated optics323.4' field of view at 1000 yards50 angle of viewUse and Handling Closed bridge configurationKnurled center focusing wheelTwist-up eyecups for use with or without eye wear18mm eye relief, 3.1mm exit pupilConstruction Details Lightweight fiberglass reinforced polycarbonate housingHousing is corrosion, temperature and impact-resistantNitrogen-filled for fogproof performance, submersible to 3.3' (1m)Rubberized armoring protects against impacts and provides slip-resistant gripInner focusing mechanism provides smooth focus while preserving waterproof sealsWeighs in at just 12.8 oz
