Pentax VD 4x20 WP Binocular Summary

The PENTAX VD 4X20 WP are multi-featured binoculars with a unique three-in-one design. As conventional binoculars, they deliver a solid, magnified view of the subject. In addition, they feature the world’s first detachable design, which allows the user to separate the two barrels in order to use them independently or jointly. Separating the barrels lets the PENTAX VD 4X20 WP function as two independent monoculars that can be shared by two observers. Or, by connecting the barrels inline, it functions as a high-power telescope with 16-times magnification.

PENTAX VD 4X20 WP Features

Detachable, three-in-one design

  • Binocular function: used as conventional binoculars to deliver a solid, magnified view of the subject at four-times magnification.
  • Monocular function: by disconnecting the two barrels, can used as two independent monoculars with four-times magnification. Unlike binoculars, which demand adjustment of pupillary distance and diopter for each user, these monoculars allow users to observe the subject with focus adjustment alone.
  • Telescope function: by connecting the two barrels inline, it functions as a 16-times telescope.

Exceptional optical performance

All reflective surfaces of the optical elements and prisms have been fully multi-coated to prevent excessive reflection. By treating roof prisms with phase coating and auxiliary prisms with super-high-reflection dielectric, multi-layer coating, this model boosts improved transmissivity and delivers outstanding imaging performance with a bright, sharp, high-contrast view of the subject with minimal flare and ghost images.

 Washable, waterproof body

Featuring weather-resistant construction* (equivalent to JIS Class 7; protected against immersion to one meter under the water), this model can be rinsed clean with water, and is usable under all weather conditions.

* Not usable in the water.


  • Exclusive neck strap, which double-functions as two independent hand straps for monoculars
  • Helicoid eyepiece rings, with single-action storage operation
  • Optional TP-3 tripod adapter (currently available) for installation on a tripod
