Don’t miss a moment. Indoor or out.

The U series consists of compact, durable models ideal for use from the field to the theater.  PENTAX quality and clarity are within reach, at a price that’s within reach, too. These compact porro-prism models feature a dual-axis, single body design with synchronized eyepiece adjustment. Aspherical lens elements give you edge-to-edge sharpness. Clear images and clearly affordable.

Fully-multi-coated optics assure 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.
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.

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.

The UP 8-16x21 Zoom and UP 10x21 and 8x21 models are offered in unique, attractive color options that match your personal style.
