The 8x21 UCF R binocular from Pentax features a clever dual-axis body design. Unlike common dual-hinge optic, the UCF R's eyepieces move simultaneously when adjusting them for viewing. This type of construction makes setting the binocular up a breeze, and it adds a significant amount of strength and stability to the entire optic.

Sporting a rubber-covered housing and sliding eye cups, the UCF R provides a secure grip and a customized view. The optical system consists of a pair of BAK4 roof prisms in a compact configuration, and super multicoated lenses for optimum viewing at all times. The 8x21 UCF R has an entry-level price-point, yet it's durable, easy to carry and use, and it delivers excellent viewing performance.
