• High-quality optics for exceptional image quality
  The new eyepieces feature an optical system with 7 elements in 5 groups that surpasses the conventional XW series to deliver sharp star images right to the edge of the field of view. 
• PENTAX original multi-coating for outstanding light transmission
  All lens surfaces that come into contact with the air are treated with the original multi-coating, while all laminated surfaces are treated with the innovative partial coating to achieve light transmission of more than 90 per cent (an astonishing 96 per cent at 550nm) across the visible lightspectrum.
• Advanced light-shielding technology for improved image contrast
  Thanks to PENTAX's advanced computer simulation technology, the XW series features a lightshielding diaphragm in the most effective position to dramatically reduce internal reflections and provide a brighter, higher contrast image.
• Weatherproof construction for all-weather viewing
  The XW Series features a JIS Class 4* weatherproof construction that allows use even in drizzle or nighttime dew.
