About Pentax 6.5 x 21 Papilio Butterfly Series Binocular

 

Pentax Papilio binoculars are the perfect choice for insect observation in the field and in museum and galleries. The enhanced observation capability of the Papilio binoculars is made possible by a Pentax Convergent Lens Optical System Engineering (CLOSE) mechanism. CLOSE automatically slides the left and right objective lenses toward the center when the focus is fixed at a short distance.
  • Revolutionary, dual-axis, single body housing with synchronized eye-piece adjustment to assure correct optical alignment for comfortable viewing.
  • Fast and easy center focusing for handling ease.
  • Helicoid eyepiece rings for extra viewing comfort.
  • Fully multi-coated optics to eliminate harmful ultraviolet rays while improving light transmission for high contrast images with no glare.
  • High-quality BaK-4 prisms transmit more light at the edges to enhance illumination.
  • Tough rubber-coated exterior provides a sure grip and protects the internal mechanisms.
  • Includes neck strap, carry case, and eyepiece lens caps.
