The PENTAX SD 7x42 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. The PENTAX SD 7x42 ED features a large six-millimeter exit pupil, making it ideal for astronomical observation.

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. The PENTAX SD 7x42 ED features a large six-millimeter exit pupil, making it ideal for astronomical observation.

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.
