Pentax extends its Porro Prism binocular line with two lower-priced, compact, lightweight, and waterproof models.

Multi-coated lenses and high-refraction BaK4 glass prisms enhance viewing the subject, creating a brighter picture in the process. For close range, a 3m focusing distance ensures a sharp, clear image.

When it comes to withstanding the elements, both binoculars meet JIS Class 6 standards for watertight designs. Specifically, each can be submerged up to a 1m depth. Added to this, rain-shielding eyepiece rings block rain and dust from the interior.

The most compact of the PCF series so far proves to be optimal for carrying and usage in nature viewing, wildlife observation, and attending sporting events. A full-body rubber coating provides a comfortable grip, while anti-fatigue viewing equally guards against eye strain. To view on your own terms, add one of the extendable eye pieces, or easily mount it onto a tripod.
