Compact 9x21 binoculars for outdoor use

The Pentax UD 9x21 binoculars weigh 195g and use a roof-prism LightPath with anti-reflection multi coatings. They are built for astronomy, bird watching, hiking, stargazing, travel and sport. Independent left and right diopter adjustment accommodates differing prescriptions. A two-tone grey and orange finish distinguishes the closed-bridge body.

Lightweight handling with coated optics

At 195g the binoculars add minimal load to a pack and the compact take-anywhere design keeps them easy to handle during extended viewing. Fully multi-coated optics and the roof-prism system maintain brightness and clarity across the field. The large focusing ring and non-slip diopter ring allow quick, precise adjustments in normal outdoor conditions.

9× magnification with 21 mm objectives

The 9× magnification makes an object at 90 m appear the same size as at 10 m, while the 21 mm objective diameter determines the exit pupil and low-light performance. Buyers who need a larger exit pupil for dawn or dusk observation, or who require a wider field of view than this aperture provides, should consider a different optical configuration.

Questions about this item

How do I adjust the focus and diopter rings without them slipping?

Both the large focusing ring and the diopter adjustment ring have a non-slip design for quick, precise operation even with damp or gloved hands.

What upkeep will the multi-coated lenses require over time?

Clean the fully multi-coated optics only with a soft brush or lens cloth; avoid solvents that can damage the anti-reflection layers.

At what distance does the 9× magnification start to show hand-shake blur during long sessions?

At 9× power an object at 90 m appears as if at 10 m, so any tremor is magnified nine-fold; a monopod or elbow brace helps during extended viewing.
