A series of new-concept model binoculars and monoculars that feature innovative functions and unique designs, beyond conventional ideas

One of these models is the world‘s first* three-in-one binocular with triple-functions: as four-times-magnification binoculars; as two independent monoculars, by disconnecting the two barrels; or as a telescope, by connecting the barrels inline. Featuring detachable construction, the left and right barrels separate from the centre, and each can be used as an individual monocular, enabling you to gaze at far-off scenery together with a companion as well as to share the same wonderful sense of excitement. The other is a compact, lightweight, high-performance monocular, providing single-handed focusing operation. With the complete kit installed, this monocular can be converted into a microscope or telescope lens for smartphones, enabling a broader range of applications. The waterproof construction realises confident usage during outdoor activities. It is perfect for viewing objects up close for nature observation or at museums.

* Based on RICOH IMAGING research ( as of July, 2020 ).

PENTAX Lens Coating Technology

Drawing on technologies cultivated in the development of a wide range of cameras and lenses, PENTAX has provided quality binoculars since 1938. We invite you to see for yourself the clear, sharp, contrast-rich view created by our world-renowned optics and innovative coating technologies.

Point 1 New Fully Multi-Coated Optics

Full application of multi-coating maximises light transmission and minimises internal glare and flare. PENTAX applies multiple layers of coating to every light-incident surfaces of lens elements and prisms on most of the models. A lineup you can rely on, from the compact U-series to flagship Z-series.

Point 2 Coating for Enhanced Light Transmission

Our high-end models have undergone a redesign, while a coating, developed with the latest film-deposition technology, has been applied to lens and prism surfaces to dramatically raise visible light transmission.

Point 3 Protects Outer Lens Surfaces from Grease and Abrasive Materials

A protective coating has also been added to protect objective and eyepiece lens surfaces from accidental drops of water, oil or dirt, ensuring they can be wiped clean with ease. (Limited to Z-series and some S-series models.)
