Product Description
With the incorporation of PENTAX-original HD coating, telescope-type optics, and
its stunning design, this super-telephoto lens delivers clear, well-defined
images of distant subjects.Outstanding image rendition of distant subjects
When mounted on a PENTAX K-mount digital camera body, this super-telephoto lens
offers a focal length of approximately 859mm (equivalent 35mm format). Since its
unique telescope-type optics require fewer optical elements than conventional
lens optics, it assures sharp, well-defined images, particularly with distant
subjects.
New, high grade HD Coating
This lens is treated with the HD Coating, a high grade multi-layer lens
coating recently developed by PENTAX. Compared with conventional multi-layer
coatings, this new coating provides higher light transmittance with reduced
reflection, to deliver sharp, clear images free of flare and ghosting, even
under demanding lighting conditions such as backlight.
Dustproof, weather-resistant construction
As a new model of the AW (All Weather) series, this lens features a dependable
dustproof, weather-resistant construction with 29 special seals to effectively
prevent the intrusion of dust and water into the lens interior. By coupling this
lens with a dustproof, weather-resistant PENTAX interchangeable lens digital
camera body such as the PENTAX K-5 II or PENTAX K-30, the user is assured a
durable, reliable imaging system that performs superbly in demanding outdoor
settings such as rain or mist, or in locations prone to water splashes or spray.
Easy control of circular polarizing filter
This lens comes with a built-in, removable filter holder in the barrel. By
mounting the C-PL (circular polarizing) filter (40.5mm in diameter; included as
an exclusive accessory) to the holder, the user can easily obtain the desired
polarizing effect simply by rotating the filter using its control ring.
New exterior design signifying HD series
The lens exterior has been painted an elegant white to minimize heat haze
generated inside the lens barrel due to long exposure to the sun. Featured in
the middle of the lens barrel, a red anodized ring serves as a distinct, radiant
symbol of the new HD PENTAX lens series. Strap lugs are made from machined
aluminum to enhance its exclusive appearance.
