A compact, portable roof-prism binocular series, providing a choice of two basic models to accommodate a wide range of applications



TOKYO, August 4, 2020,-RICOH COMPANY, LTD and RICOH IMAGING COMPANY, LTD. announced the launch of the PENTAX UD 9X21 and PENTAX UD 10X21 roof-prism binoculars. These basic models feature a compact, lightweight design for great portability, and provide a higher magnification than most other compact binoculars currently on the market.

Despite their compact, palm-sized body, these binoculars provide greater magnification than most existing compact models (six to eight times). Thanks to this high-magnification design, users can observe subjects one size larger than other models. The PENTAX UD 9X21 incorporates fully multi-coated optics -- a series of lens coatings identical to those applied to higher-class models -- to assure bright and clear viewing. The PENTAX UD 10X21 features more powerful optics with 10-times magnification, while retaining the same compact body size. With a choice of two magnifications, the PENTAX UD series assures comfortable viewing in a wide variety of applications, while excelling in cost performance.

The PENTAX UD 9X21 also provides a choice of five body colors to accommodate user color preferences.

Main Features of the new PENTAX UD

1. Compact, lightweight design

The PENTAX UD series features a compact, palm-sized body and weighs approximately 195 grams -- the lightest of all existing PENTAX binoculars. Designed exclusively for the PENTAX UD series, its compact, easy-to-hold body assures outstanding portability in a wide range of applications, from nature observation to the viewing of sports, concerts and theatrical performances.

2. Bright, clear viewing

Thanks to the incorporation of multi-coated optics designed to eliminate excessive reflection, the PENTAX UD series delivers a bright, clear view of the subject free of flare and ghost images. The PENTAX UD 9X21 features fully multi-coated optics -- a multi-layer coating applied to all reflective lens surfaces -- to assure an especially bright view of the subject.

(Note: The PENTAX UD 10X21 has a single multi-coated lens, while other lenses are treated with a single-layer coating.)

3. Other features

  • ・A minimum focusing distance of approximately three meters for a sharp view of close-range subjects
  • ・Nonslip diopter rings for easy, error-free diopter adjustment
  • ・Optional TP-3 tripod adapter (currently available) for installation on a tripod

♦ Designs and specifications are subjects to change without notice.
