Conceived, designed, and constructed for outstanding performance in low-light conditions when many animals are most active, the Steiner Optics 8x56 ShadowQuest Binoculars combine multiple technologies and features to ensure clear and crisp views from first light through twilight.

Their performance starts with the combination of moderate magnification and oversized objectives. At 56mm, the objectives draw in the copious amounts of light required for seeing in low light, while the 8x power produces both a large exit pupil and wide angle of view. A wide exit pupil ensures that the light leaving the eyepieces completely cover the user's pupils when they are fully dilated in low light to take full advantage of the wide viewing angle. The optics are fully multi-coated with Steiner's proprietary Diamond Night lens coatings, which are engineered to maximize light transmission through the light path. All of these features, when coupled with the traditional Porro prism light path, present the user with an immersive observational experience defined by bright and clear high-contrast views and accurate color rendition. Winged eyecups conform to the user's face and eye sockets to block stray peripheral light and improve the contrast of the view while limiting distractions.

Complementing the optical performance are construction details that allow the ShadowQuest to withstand the rigors of the outdoors. These details begin with Steiner's Sports-Auto-Focusing System, which allows the user to focus each eyepiece, just one time, and eliminates the need to refocus again regardless of how near or far the subject is—or if it is moving. Speaking to the low-light-use purpose, an innovative photoluminescent Lumiclip system is employed that glows with just enough light to be able to find them in low or no light. The chassis is made of a lightweight and impact-resistant Makrolon polycarbonate material that is wrapped in an oil, petroleum, and chemical-resistant NBR synthetic rubber armor that offers improved grip security, especially in cold and wet weather. Their optical tubes are nitrogen-filled and O-ring sealed to be waterproof to a depth of 16 feet and resistant to internal fogging when moving through extreme temperature changes and environmental conditions.

From dawn to dusk to piercing thickly wooded stands, the ShadowQuest binoculars have been engineered to provide outstanding performance in the most challenging light and environmental conditions possible.

Optical Performance

  • 8x magnification
  • Large 56mm objective lenses
  • Traditional Porro prism optical path affords a richer depth of field versus similar roof prisms
  • Proprietary Diamond Night lens coating formula uses rare-earth materials to maximize light transmission to greater than 96% for improved low-light performance
  • Proprietary Nano-Protection protects lens surfaces, enabling water to bead off, and preventing dirt from sticking, to provide clearer views in all weather conditions
  • Floating prism mounting system helps to absorb impacts to avoid damage and maintain optical path collimation
  • Ultra-wide 67° apparent angle of view
  • 441' field of view at 1000 yards

Use and Handling

  • Lumiclip system: Luminescent clip glows with just enough light to locate the binoculars in the dark
  • Fold-down rubber eyecups for comfortable use with or without eyewear
  • Ultra-long 24.4mm eye relief makes long-duration glassing sessions comfortable
  • Large 7mm exit pupil is optimized for low-light conditions to completely cover pupils when they are fully dilated to avoid vignetting of the view
  • Sports Auto-Focusing System:
  • Individual eyepiece focusing
  • Requires only one initial individual focus adjustment per user
  • Eliminates the need for refocusing for targets at ranges from 22 yards (20m) to infinity
  • Enables the tracking of fast targets without the need to refocus

Construction Details

  • Lightweight and impact-resistant Makrolon polycarbonate chassis
  • Nitrogen-filled and O-ring sealed to be waterproof to a depth of 16' (5m) and resistant to internal fogging when moving through extreme temperature changes and environmental conditions
  • ErgoFlex winged angled eyecups block stray peripheral light from interfering with views while improving contrast and limiting distractions
  • Oil, petroleum, and chemical-resistant NBR synthetic rubber armor offers improved grip security, especially in cold and wet weather
  • Broad -40 to 175°F operating temperature range
