Anyone seeking the perfect choice to observe insects or animals in the field must look into Pentax Papilio binoculars. These outstanding items feature enhanced observation features made possible by an advanced Lens Optical System mechanism made by Pentax. What this basically does is to slide the right and left lenses to the center when at a short distance the focus is fixed.

The system known by the abbreviation C.L.O.S.E. permits focus to 1.6 feet. Also, the internal mechanisms are protected by a strong rubber covered exterior. Comfortable viewing is insured by a dual-axis that is truly revolutionary plus a body housing with an eye piece adjustment which is synchronized. Handling ease is provided by center focusing which is fast and easy. Also, harmful ultraviolet rays are eliminated by multi-coated optics while light transmission is improved for images of high contrast with no flare or glare. BaK4 prisms of very high quality provide more light to enhance illumination making it much easier to view when the light is dim.
