3way ~Monoculars and telescope~

Enjoy in three ways that suit your purpose and the scene (binoculars, monoculars, telescope). All of these are in this single item. These high-performance three-in-one binoculars are only possible with an optical manufacturer.

14X binoculars

The 4X magnification is convenient for watching stage performances, concerts, and sporting events. They feature the right field of view for scenes with movement and for situations where you want to view the entire scene.

  • Bright view and minimal handshaking
  • Thumb grip for secure hold
  • Compact and highly portable

24X monoculars

This option is perfect for viewing museum exhibits up close or sharing a scene with someone else.

  • Observe by seeing up to 50 cm close to the object.
  • Bright view and minimal handshaking
  • Rubber grip for secure holding. Easy to handle compactness.

316X telescope

When 4X magnification is not enough for viewing stars or far-away scenery, connect each monocular’s end to make a 16X telescope.

  • Focus with the front focusing ring
  • Use the optional tripod adapter (TP-3) with
    a tripod for a steady, blur-free view

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.

1 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 in light transmission, reducing flare and ghosting, and delivering bright, sharp, high-contrast optical performance.

2 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.
