Pentax 8-16x21 U-Series UP Binocular (Black)

Pentax 8-16x21 U-Series UP Binocular (Black)

The compact and lightweight black 8-16x21 U-Series UP Binocular combines aspherical optical elements and BAK4 Porro prisms to deliver edge-to-edge image sharpness with a wide angle of view. The optical elements are also fully multicoated to provide a high transmission of light. With an 8-16x range of magnification and 21mm objectives, you obtain a wide zooming range and a compact form factor. You can easily spot your targets with a 5° angular field of view at 8x magnification and quickly zoom in on them with the optical zoom. To reduce image jitter at high zoom factors or for prolonged observations, you can connect the binocular to a tripod via an integrated 1/4"-20 socket. In addition to observing distant scenes, birds and game, the minimum focus of 9.9' allows you to study in detail close objects like animal footprints, marks or landscape features. The binocular also features a 2.6-1.3mm exit pupil range, a 14-11mm eye relief range, an interpupillary and a diopter adjustments.

The binocular is very compact, lightweight, and features a single piece frame that houses objectives, which allows for a synchronized interpupillary adjustment. To accommodate eye glasses wearers, the binocular offers sliding rubber eyecups. Also included are a carrying case, a neck strap, and eyepiece covers.
