The Pentax 9x42 DCF BR Binoculars are heavy-duty roof-prism binoculars featuring high-performance optics, a waterproof construction allowing fresh-water rinsing, and an ergonomic body design for a comfortable hold. Combining outstanding optical performance and value with a compact, lightweight, carry-anywhere body, the Pentax 9x42 DCF BR Binoculars can be used in a wide range of applications including nature observation, bird-watching, sports viewing, hunting and more.
9x42 DCF BR additional features:
smc Multi-Layer Lens Coatings:
To improve the overall transmission and resolution, lens-coatings are used to reduce reflection and loss of contrast.
With the use of Super Multi Coated lenses, Pentax achieves high efficiency allowing light transmission of up to 98%!
The Pentax smc coating is a complex and sophisticated 7-layer coating that corrects light-transmission over the full light spectrum.
It is renowned throughout the optical industry.
A prism is a complex optical element necessary to correct the image to right way up,
and reduce overall length of the binocular.
In a prism, light travels through complicated angles and so the quality of the prism glass used is of significant importance.
Pentax uses exclusively high-indexed BaK4 prisms; made of very pure Barium glass.
Challenge the Elements:
Pentax is one of the few companies who physically test their sport optics against both recognised JIS norms to classify the degree of resistance to environmental influence.
They define and test against: JIS 6; The product is fully water proof and has maximum protection against rain, dust, moisture or internal fogging due to extreme temperature fluctuations.
Their binoculars are double O-ring sealed as well as nitrogen purged so that temporary immersion into
1 meter of water will have no negative effects.
Phase Corrective Coatings:
In roof prism binoculars, light rays are mirrored several times which can result in reduced light transmission.
By adding an additional Phase Correcting coating the light-rays frequencies are corrected to their original values.
Pentax use the latest Phase Correction coating on all their roof prism binoculars.
The Inner Focus function is critical to low-maintenance and long life guarantee. Exposure to airborne particles and moisture is avoided, thereby ensuring that no outside
influences can penetrate the binocular housing and disrupt functionality.
Helicoid-type, extendible eyepiece rings with a click-stop adjuster for quick, easy adjustment of eyepiece position
Minimum focusing distance of approximately 2.5 meters (8.25 feet) for a clear view of up-close subjects
Rain-shielding eyepiece caps to prevent the intrusion of dust and raindrops during observation
Long eye relief to assure comfortable observation over extended periods, even for eyeglass wearers
Tripod socket (the optional TP-3 Tripod Adapter required for on-the-tripod observation)
These models may not be used for underwater viewing.
