Focus:central
Prism:Roof, BaK-4
Weight:195 g

Compact and lightweight (only 195 g) binoculars with 9x magnification, which can easily fit in a purse or pocket thanks to their small dimensions (108x87x38 mm). The objective lenses, which have a diameter of 21 mm, are made of barium crown BaK-4 - a special optical glass with a low light dispersion coefficient, due to the use of which the effect of chromatic aberration is significantly reduced.

The lenses are coated with a multi-layer anti-reflective coating. Therefore, owners of Pentax UD 9x21 binoculars see a picture with a clear, contrasting and evenly light image across the entire field of view. The body of the device is made of plastic. A special feature of this model is its stylish design with several color options: from classic black to original pink and orange.
