You'll see sharp details of distant objects with the 10x magnifying power, and the 32mm objective lenses gather plenty of light while allowing a compact and lightweight form factor. Extra-low dispersion glass corrects for chromatic aberration to ensure colours are accurately rendered, and fully antireflective-coated optics maximize light transmission through the entire optical path to make views appear bright and crisp, especially in low light.Complementing the optical performance is a housing that is built for a lifetime of rugged outdoor use. The chassis is made of grippy, comfortable-to-hold thermoplastic elastomer resin. The optical tubes are nitrogen filled to resist internal fogging from sudden temperature changes. With the optional TP-3 adapter, you can mount the binoculars on a tripod for hands-free, no-shake viewing. Whether birding, sightseeing, exploring the backcountry, or seeing the stage at a music festival, this optic will assure a great view.Bright, Clear Viewing:The AD ED provides a bright, clear view of the subject with minimal glare and ghost images, thanks to the application of a full multicoating process to all lens surfaces, and a special coating designed to optimize light transmittance.ED Glass Optical Elements:As the first models in the PENTAX A series to incorporate ED (extra-low dispersion) optical elements for effective compensation of chromatic aberration, these binoculars deliver a sharp, high-contrast, blur-free image.Compact, Lightweight Design:While incorporating objective lenses with a 32mm diameter to assure superb operability, these models are designed to be compact and lightweight for easy carrying in a wide range of applications, from bird watching and nature observation to the viewing of sports events and concerts.Additional Features:+Exterior housing made of thermoplastic elastomer resin to improve holding comfort and prevent accidental slippage+Easy-to-operate diopter adjustment mechanism with a non-slip, ring-type adjuster+Waterproof construction equivalent to JIS Class 6 standards for dependable use in adverse weather conditions+Nitrogen-filled design to prevent interior lens surfaces from fogging due to sudden temperature changes+Extendable eyepieces for effortless shift between in-use and storage positions+Easy mounting on a tripod, in combination with the optional TP-3 Tripod AdapterIN THE BOX:+Pentax AD 10x32 ED Binocular+2 x Objective Lens Cap+Eyepiece Lens Cover+Neck Strap+Carry CasePRODUCT HIGHLIGHTS:+Prism Type - Roof+Magnification - 10x+Objective Lens Diameter - 32 mm+Angle of View - 6 (Actual)+Field of View - 315' @ 1000 yd / 104.6 m @ 1000 m+Minimum Focus Distance - 9' / 2.7 m+Exit Pupil Diameter 3.
