Main characteristics :


New Multi-Coated Lens Coating

The multi-coated lens coating allows for better transmission of light through the lenses and prevents the risk of flare and ghost images. PENTAX applies several layers of coating to each surface of the lenses, the Prism and this for the entire range of binoculars. This treatment guarantees better light transmission for sharper aiming.

BaK4 prism

Thanks to its incredible refractive index, the BaK4 glass prism, found in all PENTAX binoculars, is highly regarded for its circular pupil exit and absence of vignetting.

Aspherical elements

The sharpness over the entire surface of the lens thanks to the aspherical elements used is an essential element for greater viewing comfort. Thanks to its special shape, the dispersion index is reduced to a minimum.

50cm MACRO FUNCTION

Absolutely unique and innovative, the macro focus of the Papillio allows the user to observe objects at a distance of only 50 cm! Users are literally immersed in their surroundings and are nothing more than observers from a distance. Much appreciated by entomologists, and all those who love butterflies, spiders, flowers, etc.

Construction with internal focus

This design is ideal for waterproof models that require completely sealed construction. This also contributes to maximum reduction in size and weight and improves the center of gravity as well as reliability.

Long eye relief

The comfortable eye relief found in almost all PENTAX binoculars allows the user to maintain the entire field of view clearly and comfortably. This is particularly beneficial to wearers of glasses, and allows long periods of observation without straining the eyes.

Other Features

Windshields with 3 retractable positions that allow precise adjustment for maximum aiming comfort. Rubber exterior finish for shock and impact protection.
