The Pentax 8x21 UP Binoculars deliver impressive optical performance in a compact, lightweight design. Ideal for travel, sports, and nature watching, they combine portability with sharp, bright images that bring every detail to life.
Featuring aspherical optical lenses, BAK4 Porro prisms and fully multicoated optics, these binoculars offer edge-to-edge clarity and excellent light transmission. With 8x magnification and 21mm objective lenses, you get powerful, steady viewing without the bulk.
A central focus wheel allows quick, precise adjustments while the 6.2° wide field of view helps you track subjects easily. The minimum focus distance of 9.2 ft lets you observe close details like tracks or textures with impressive clarity.
The single-piece frame provides smooth interpupillary adjustment and a stable feel in hand. Sliding rubber eyecups make them comfortable for glasses wearers, and the contoured grip ensures secure handling during extended use.
Compact enough to fit in your bag yet powerful enough for distant viewing, the Pentax 8x21 UP Binoculars are perfect for any outdoor enthusiast.
Includes: carrying case, neck strap and eyepiece covers.
