Pentax SD WP overview

  • 1Description

Designed for both astronomical and terrestrial use, Pentax's 20x60 S-Series SP WP Binocular 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 binocular sports 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. Its 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 binocular can be mounted on a tripod using an optional adapter.

    Pentax SD WP reviews

    20x60 S-Series SP WP Binocular is rated 4.8 out of 5 by 4.
    Rated 5 out of 5 by from Pentax 20x60 Binocular Great binocular; focus is sharp objects are clear even at dusk or low lighting. Can be held with ease and is not too big or bulky.

    Rated 5 out of 5 by from Great Binocular I think these are great binoculars. They are not too heavy and not too light at 3 pounds. Optics are good. The price is great. I wish Pentax would make a 20x80.

    Rated 4 out of 5 by from Good for the price This is a good binocular for the price. The lens is not as clear as I expected from Pentax and not as powerful for 20x60.

    Rated 5 out of 5 by from Best for the price Ive been using this binocular for a couple of years now.  It is possibly a 4-star binocular (compared to Nikon), but considering the great price, worth 5-star rating.  Its not your all-around binocular for everyday use.  I actually use it as a low powered scope.  Although its 20x, its as useful as a 30x scope because of better field of view and three dimensional effect.  Eye relief is so long that I need to adjust them a notch even with glasses.
