The UCF Zoom II is multi-functional wizard. In one compact and lightweight binocular you have the power to observe with 8 to 16x magnification by simply turning the central wheel. Add to this the aspherical lens elements for edge-to-edge sharpness, BaK4 prisms, and fully multi-coated lenses to enhance brightness & contrast, and you have the perfect travel companion who won’t let you miss a thing.
Larger, further, faster: UCF ZOOM series binoculars offer unmatched versatility. Zoom yourself across the distances with variable magnifications of 8 to 20 times or 8 to 16 times. This variable enlargement factor makes these small, light porro prism binoculars particularly well-liked and versatile companions. The high eye-point relief of UCF ZOOM series means that eyeglass wearers can also enjoy the advantages and benefits of these binoculars fully and completely.
Aspherical lens elements providing edge-to-edge sharpness
Edge-to-edge sharpness is a vital element to comfortable viewing. To achieve this we utilise aspherical lens elements in our eyepieces. This is a specially shaped lens design that reduces aberration to a minimum.
The Inner Focus function is critical to low-maintenance and long life guarantee. Exposure to airborne particles and moisture is avoided, thereby ensuring that no outside influences can penetrate the binocular housing and disrupt functionality.
Inverted porro prism design
This can be recognised with the eyepiece positioned off-line from the objective lens. The advantages of this design are that it is less expensive and has good optical quality.
High Quality BaK4 prism to enhance transmission and resolution
A prism is a complex optical element necessary to correct the image the right way up and reduce overall length of the binocular. In a prism, light travels through complicated angles and so the quality of the prism glass used is of significant importance. PENTAX uses exclusively high-index BaK4 prisms, made of very pure Barium glass.
