The Pentax SD 10x42 ED roof-prism binoculars feature large, 42-millimeter diameter objective lenses and ED glass elements –also a first for the S-series – to deliver sharp, high-contrast viewing, even in lowlight conditions. They provide minimal glare and ghosting thanks to the application of a full multi-coating process to all lens surfaces and a special coating designed to optimize light transmittance. They are designed with a dependable, waterproof body for use in almost all weather conditions.

Bright, clear viewing

As with Pentax’s top-end Z-series models, these new models provide sharp, high-contrast images with minimal glare and ghost images, thanks to the application of a full multi-coating process to all lens surfaces and a special coating designed to optimize light transmittance. They also feature large, 42-millimeter diameter objective lenses to deliver a bright, clear view even in unfavorable lighting conditions, such as in twilight.

ED optical elements

As the first Pentax S-series models to incorporate ED (Extra-low Dispersion) optical elements for effective compensation of chromatic aberration, these binoculars deliver a sharp, high-contrast, blur-free image of the subject.

Dependable waterproof construction for use in harsh conditions

Thanks to their dependable waterproof construction* (equivalent to JIS Class 6 standards for watertight designs submersible to a depth of one meter), these models can be used in almost all weather conditions and can be easily rinsed clean with water. The nitrogen-filled design prevents the interior lens surfaces from fogging caused by sudden temperature changes.

Other 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. Extendible eyepieces for the effortless shift between in-use and storage positions. Easy mounting on a tripod, in combination with the optional TP-3 Tripod Adapter.
