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.

Technology  ~Reliable performance~


Enjoy superb reliability with the technology and know-how of PENTAX cultivated over a long period of years. This model can be used with satisfactory, whether as binoculars, monoculars, or a telescope.

Superb optical performance 

Full multi-coating is used on the surface of all lenses and  prisms to prevent the reflection of unwanted light. Also, phase-coated roof-prisms and super-high-reflection dielectric multi-layer coating on the auxiliary prism provides dramatic improvements on light transmission, reducing flare and ghosting, and delivering bright, sharp, high-contrast optical performance. 

Washable waterproof performance

The waterproof construction* (equivalent to JIS Class 7; protected against immersion to one meter under the water) makes it possible to wash these binoculars and use them in any weather. With this construction, you can use them in the rain, near waterfalls, and in other outdoor activities. 

*Not usable in the water

Accessories  ~Pursuing ease of use~ 


Newly designed accessories to fit the original concept binoculars perfectly.


Stylish exclusive case, with green stitching, to match the lens ring design as an accent.


Like the binoculars, this exclusive strap can also double-function as a neck strap for binoculars, and two individual hand straps when used as monoculars.

The world’s first* 3-in-1 binoculars, to share the excitement.

Original concept binoculars that can be shared as monoculars when disconnected, and used as a telescope by connecting the barrels inline.
