Pentax DCF waterproof binoculars

Pentax have announced the addition of two binoculars to the popular Pentax DCF series: the 8x28 DCF MP and the 10x28 DCF MP. Despite their compact, lightweight design, these new models feature a fully water-shielded, nitrogen-filled body and high-performance roof-prism optics incorporating multi-coated optical elements and phase-coated prisms. Their waterproof design makes them ideal for use on or around the water, as well as for observations in harsh weather and extreme climates.

The waterproof body of these DCF MP models is rated JIS Class 6, allowing the user to wash them clean when they get dirty or are accidentally soaked in salt water. The body is filled with nitrogen to prevent fogging caused by sudden temperature changes.* Pentax's original inner-focus optics not only makes them smaller and lighter, but also assures a sharp, bright image without distortion. In addition, these models incorporate a host of user-friendly features to make viewing pleasant and fatigue-free.

Major Features of Pentax DCF MP Series
1. High-resolution phase-coated roof prisms
Normally available only in the most expensive models, phase-coated prisms effectively cancel the phase difference created on the wave front of light passing through the prisms, thus producing sharp, high-contrast images with much improved resolution.

2. Multi-coated optical elements
All optical elements are treated with a special multi-layer coating to produce clear, bright images without flare. As a result, these new models are excellent choices for bird watching and hunting in the woods.

3. Waterproof body
In addition to the JIS Class 6-rated waterproof construction, these models are filled with nitrogen to eliminate fogging due to sudden temperature changes. As a result, they can be used safely under extreme weather conditions such as rain or snow.
