PENTAX PentaBright Technology: Your Best
Solution for Top-Quality Viewing
The complex science of optics requires attention to
the type and quality of glass, design, construction,
eye relief, tube alignment, sealing against moisture,
and user comfort. PENTAX has been an innovator
in the field of optics for over 90 years, so no one
knows optics better than PENTAX. We pioneered
multi-layer lens coatings which greatly increase light
transmission efficiency that delivers bright, high
contrast images without flare. This establishes the
core of our PentaBright technology.
The Backbone of PENTAX’s
Technological Excellence
Super-Multi-Layer Coating
All optical elements within every PENTAX product
are treated with our time-proven multi-layer coating
which not only improves light transmission to deliver
bright, high contrast images without flare, but also
reduces eye fatigue even during extended observation.
Durable Construction
Every PENTAX Sport Optics instrument is built
to the highest of standards using some of the
toughest materials available. PENTAX binoculars
and spotting scopes are encased in highly durable
rubber-armoured housings, which are designed to
protect the optical mechanisms inside from shock
and damage, while making them easier to hold.
PENTAX waterproof products are fully sealed and
feature airtight construction. They are purged with
laboratory grade nitrogen to provide a fog proof
view in the harshest weather conditions, and extreme
temperatures.*
*Not designed for underwater use.
Long Eye Relief
The long eye relief offered in all PENTAX Sport
Optics allows the viewer to see the entire field
of view clearly and effortlessly. This is especially
beneficial to eyeglass wearers, and allows viewing for
extended periods of time without added eye strain.

High-Refraction BaK4 Glass Prism
Due to its outstanding refraction index, the BaK4
glass prism is highly acclaimed for its perfectly round
exit pupil and clear, unvignetted image.
Aspherical Optical Elements
The PENTAX aspherical optical elements greatly
improve 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.
Inner-focus Optical Design
Incorporated in all DCF series models, plus the UCF
and PCF WP II 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 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.

Straight-Line Optics for
the Highest Quality and Performance
The PENTAX DCF series meets a diverse set of
needs by offering six different models: the superior
quality of the DCF ED, the time proven DCF SP,
durable DCF WPII, heavy duty DCF HRc, value
packed DCF HS and the compact DCF LV and
DCF SW.
All DCF series models feature high-performance
straight-line optics with high-resolution phase-coated
roof prisms and multi-coated optical elements.
Several models also come equipped with nitrogenfilled waterproof construction (JIS Class 6), all with
full-body protective rubber-armoured housing and a
sophisticated inner-focus optical design.
The PENTAX DCF series is the best choice for
uncompromising observers who demand optimal
image quality under all viewing conditions.
