Quick Overview

Combining high-resolution optics with fashionable, streamlined bodies, these compact, lightweight 8x21 UCF R and 10x21 UCF R offer comfortable viewing and outstanding portability in a wide range of casual observations, both indoors and outdoors.

The UCF R-series models combine the PENTAX-developed dual-axis eye-distance adjustment system for precise alignment of the lens barrels, high-refraction BaK4 glass prisms, multi-coated optical elements and aspherical eyepiece lens elements to deliver high-quality images, even under poor viewing conditions. Their compact, lightweight bodies are encased in a protective rubber housing for extra protection against dust and shock. Other user-friendly features include a short minimum focusing distance of approx. 2.8 meters/9.2 feet, extendible eyepiece rings and a diopter adjuster with a click-stop center pointer.
