Pentax's 9x28 A-Series AD WP Binocular features 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. It is also temperature-resistant allowing for its 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. Its 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.
