Features: • New Multilayer lens treatment • Inverted Porro prism • Aspherical elements • High-quality BaK4 prism for better light transmission and better definition • Dual axis with interpupillary adjustment • Rubberised finish • Draw eyecups • Central and lockable diopter adjustment • New Multilayer lens treatment • The multilayer lens treatment allows better light transmission through the lenses and prevents the risk of Flare and Ghost images (stray light). PENTAX applies several layers of coating to each lens surface, prism, and for the entire range of binoculars. This treatment ensures better light transmission for a clearer view.
BaK4 Prism Thanks to its incredible refractive index, the BaK4 glass prism, found in all PENTAX binoculars, is highly appreciated for its circular pupil output and absence of vignetting.
Aspherical elements The sharpness over the entire lens surface thanks to the aspherical elements used is a key factor for greater viewing comfort. Thanks to its special shape the dispersion index is reduced to a maximum.
Construction with internal focusing This design is ideal for waterproof models that require a completely sealed construction. This also contributes to a maximum size and weight reduction and improves the center of gravity as well as reliability.
Other features Eyecups with 3 retractable positions that allow precise adjustment for maximum viewing comfort. Rubber exterior finish for protection against shocks and impacts.
