Aspherical Optical Element
The PENTAX-developed aspherical optical
element greatly improves image brightness
and sharpness, while minimizing disturbing
distortions.
High-Resolution Phase Coating
The roof prisms of all DCF-series models are
specially treated with high-resolution phase
coating. Previously incorporated only in the
most expensive models, this special process
cancels the phase difference created on the
wave front of light passing through a roof
prism, thus producing sharp, high-contrast
images with much improved resolution.
Waterproof Construction
Featuring an airtight, nitrogen-filled
waterproof construction, all DCF-series
models, plus the PCF WP and PIF models and
the spotting scopes, are especially designed
for use on and around the water and at
extreme temperatures. The UCF WP models
also feature a waterproof body to protect the
internal mechanisms against rain, water and
moisture.*
* These binoculars and spotting scopes are not designed for
underwater use and should not be submerged in water.
Protective Rubber Housing
Most binoculars and all spotting scopes are
encased in highly durable rubber housings,
which are designed to protect the optical
mechanisms inside from shock and damage,
while enhancing holding comfort and
maneuverability even under adverse
conditions.
Inner-Focus Optical Design
Incorporated in all DCF-series models, plus the
UCF WP and PCF WP models, this sophisticated
optical design is ideal for waterproof models
that require a fully airtight body construction.
It also contributes to a considerable reduction
in size and weight and improves overall
balance by minimizing a weight shift during
focusing.
Functional, Maneuverable Body Design
The body and optical mechanism of PENTAX
binoculars and spotting scopes are
computer-designed to ensure the easiest
handling possible and minimize overall size
and weight, without sacrificing optical
performance.
Long Eye Relief
The long eye relief offered in most PENTAX
binoculars and spotting scopes allows the
viewer to check the entire field of view clearly
and effortlessly. This feature is especially
beneficial for eyeglass wearers.
