Premium optical features including extra-low dispersion glass make the Pentax SD 7×42 ED Binocular a great choice for all-around use. You’ll see sharp details of distant objects with the 7x magnifying power, and the 42mm objective lenses gather plenty of light for a bright image even in low-light conditions including at dusk, dawn, or under deep cover. The ED glass corrects for chromatic aberration to ensure accurate colors and high contrast, and fully antireflective-coated optics maximize light transmission through the entire optical path to make views appear bright and crisp.
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, hunting, exploring the backcountry, or seeing the stage at a music festival, this optic will assure a great view.
Bright, Clear Viewing
The SD 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. They also feature large, 42mm diameter objective lenses to deliver a bright, clear view even in unfavorable lighting conditions such as twilight, and a large 6mm exit pupil, so you can even use them for astronomical observation.
ED Glass Optical Elements
As the first models in the PENTAX S 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.
