All PCF WPII-series models offer a durable aluminum-diecast body with a full-body protective rubber housing, high-performance optics combining high-refraction BaK4 glass prisms and fully multi-coated optical elements, aspherical optical elements in the eyepiece optics, PENTAX-original inner focusing arm design with focus-lock mechanism, helicoid-type extendible eyepiece rings, a long eye relief of 20mm or longer, and rain-shielding eyepiece caps. Their fully water-shielded, nitrogen-filled construction ensures excellent waterproof capability (equivalent to JIS Class 6).
This series consists of four high-performance, waterproof models: the 8x40 PCF WPII, with 40mm objective lenses, the 10x50 and 12x50 PCF WPII with 50mm objective lenses, and the 20x60 PCF WPII with extra-large 60mm objective lenses.
The PCF WPII series are ideal for use around and on the water, as well as for observations in harsh weather and extreme climates.
* These binoculars also accept an optional tripod adapter (TP-3 or N) for quick tripod mounting and removal. PCF WPII models are not designed for underwater use, and should not be submerged in water.
