Compact, lightweight, waterproof porro-prism binoculars designed for easy, bright viewing of nature, wildlife and sports events




RICOH IMAGING COMPANY, LTD. is pleased to announce the launch of new series of porro-prism binocular the PENTAX PCF CW. The new series consisting of two models boasts the smallest body in the PENTAX PCF lineup and solid waterproof construction, making it ideal for a variety of outdoor and indoor activities.

Main Features

1.Bright, clear viewing

The PCF CW series provides a bright, clear view of the subject, thanks to the incorporation of full multi-coating lenses (a coating applied to all lens surfaces) and high-refraction BaK4 glass prisms.

2. Compact, lightweight design

By employing 30-millimeter-diameter objective lenses, the PCF CW series assures both a compact, lightweight body and bright subject image. In fact, the PCF CW series has the most compact and lightweight body in the PENTAX PCF binocular series, making it easy to carry and assuring optimum viewing comfort -- not only for outdoor activities, but also for indoor sports events and theatrical performances.

3. Waterproof construction for easy rinsing

Thanks to the dependable waterproof construction* (equivalent to JIS Class 6 standards for watertight designs submersible to a depth of one meter), the PCF CW-series models can be easily rinsed clean with water. This means that they can be used in almost all weather conditions. The nitrogen-filled design prevents interior lens surfaces from fogging caused by temperature difference.

* The PCF CW series cannot be used for underwater viewing.

4. Full-body rubber coating

The black rubber coating applied to the entire body of PCF CW series binoculars not only provides a high-quality appearance, but also enhances holding comfort and durability.

5. Long eye relief for fatigue-free viewing

Since the PCF CW series offers a long eye relief (the distance between the eyepiece and the viewer's eye), it assures comfortable, fatigue-free viewing in extended observations, even for eyeglass wearers.

6. Other features

  • ・Extendible eyepieces with four click stops to optimize viewing comfort
  • ・A minimum focusing distance of three meters for a sharp view of close-range subjects
  • ・Easy mounting on a tripod, in combination with the optional Tripod Adapter N or TP-3
  • ・Rain-shielding eyepiece rings to prevent the intrusion of rain and dust
