Accelerate your outdoor adventures with the Pentax HD-DA* 11-18mm f/2.8 Lens with Binoculars Kit from B&H, which pairs the weather-sealed wide-angle zoom lens with the 20x60 S-Series SP WP binoculars.
Covering a versatile range of wide-angle focal lengths, the HD Pentax DA* 11-18mm f/2.8 ED DC AW from Pentax is a 17-27.5mm-equivalent zoom for APS-C-format cameras. The lens's wide design and bright f/2.8 maximum aperture make it particularly well-suited to astrophotography applications, as well as landscape and interior shooting. The optical design incorporates a series of aspherical and low dispersion elements, which help to control distortion and color fringing for improved sharpness and clarity, and an Aero Bright II Coating has been applied to benefit contrast and color accuracy. Additionally, a Super Protect Coating, along with a weather-sealed design, make this lens suitable for use in trying weather conditions.
Designed for both astronomical and terrestrial use, Pentax's 20x60 S-Series SP WP Binoculars can be used with confidence in all weather and conditions. The large oversized 60mm objectives are fully multicoated to reduce reflection and maximize light transmission through the entire optical path. Utilizing the traditional porro prism configuration gives scenes a rich depth of view for an immersive observation experience and provides a comfortable feel in the hand with a lot of surface area to maintain a sure grip. The large objectives and coatings maximize the amount of light getting to the user's eyes for exceptional low-light capabilities.
Complementing the optical performance are construction details made for the outdoors. The optical tubes are nitrogen-filled and O-ring sealed for fogproof performance and to make them submersible to as much as 3.3'. The binoculars sport a generous 20mm eye relief and the fold-down eyecups seal against the ocular cavity to block stray peripheral light which can dim images and affect night-adjusted vision. Their over-sized objectives add weight and bias the center of gravity forward making user fatigue a concern and hand-shake a possibility, so to aid long observation sessions, the binoculars can be mounted on a tripod using an optional adapter.
