Pentex 8-16x21 UP Zoom Series Binoculars (Black)

Pentax quality and clarity are within reach, at a price that’s within reach, too. The compact porro-prism 8-16x21 UP Zoom Series Binoculars from Pentex feature a dual-axis, single body design with synchronized eyepiece adjustment. Its aspherical lens elements give you edge-to-edge sharpness. Fully-multi-coated optics ensures maximum light transmission resulting in high quality viewing. Every surface of every element is fully-coated minimizing internal glare and flare and giving a bright clear view.

Unique Uni-Body Design

Unique Uni-body design enhances durability by locking objective lenses in a single housing and synchronizing the eyepiece movement. This minimizes moving parts and assures these binoculars will function properly and clearly for years to come.

Aspherical Lens Elements

Aspherical lens elements, which are critical in compact binoculars, provide exceptional edge-to-edge sharpness. This assures that items on the edge of your field of view are just as sharp as those in the center.
