## Long description

Binoculars Pentax UP 10x21 are compact, lightweight 10x binoculars with a 21 mm objective diameter and BK-7 Porro prisms. The inverted porro-prism, dual-axis single-body construction with synchronized interpupillary distance (IPD) adjustment and protective rubber housing makes these binoculars suitable for portable outdoor use while providing clear images with good light transmission.
Advantages
Fully multi-coated optics on every air-to-glass surface increase light transmission and reduce flare and ghosting. Aspherical eyepiece lens elements minimise aberrations to deliver edge-to-edge sharpness. The inner-focus optical design protects internal components from dust and moisture, supporting low maintenance and longer service life. Pull-up eyecups and a lightweight, compact form factor enhance portability and everyday usability.
Suitable for
Hiking and nature walks
Birdwatching and wildlife observation
Outdoor events and sports
Travel and compact everyday carry

How to use
Adjust the synchronized IPD until you see a single circular field of view, then focus using the central focusing mechanism or individual eyepiece if available. Use the pull-up eyecups for comfortable eye relief when not wearing glasses. Hold the binoculars steady with both hands or use a neck strap to reduce shake during prolonged observation. After use in wet or dusty conditions, wipe the exterior housing with a soft cloth and store the binoculars in a dry place.
Usage recommendations
For best image quality, use these binoculars in daylight or well-lit conditions due to the 21 mm objective and 2.1 mm exit pupil. Avoid exposing the instrument to heavy rain for extended periods; while the inner-focus design limits internal contamination, the unit is not designed for prolonged submersion.
