The Pentax UP 8x21mm binoculars deliver 8x magnification through a Porro prism design in a compact 3.26″ × 4.33″ × 1.9″ footprint, weighing just 7.4 ounces. The 21mm objective lens produces a field of view of 354 feet at 1,000 yards with 13mm of eye relief, making them comfortable for extended viewing. A uni-body construction locks the objective lens in a single housing and synchronizes eyepiece movement to enhance durability. The optics feature aspherical lens elements that maintain sharpness across the entire field of view, not just the center. Center focus with a sliding eyepiece ring allows quick focusing down to 9.24 feet, while the 2.6mm exit pupil and 6.7 relative brightness index suit them for daytime use. A carrying case is included.
