Two New Pentax K-Mount Lenses
Big-range zoom and super telephoto
Exceptional image description
Incorporating
two extra-low dispersion (ED) elements in its optics, this zoom lens
delivers bright, high resolution images, even on the edges, while
effectively minimizing chromatic aberration.
Other features
• Minimum focusing distance of 1.6 ft. (0.49m) over the entire zoom range
• Rounded diaphragm delivers precise control while producing a smooth,
beautiful bokeh (out-of-focus rendition), minimizing the streaking
effect of point light sources
HD PENTAX DA 560mm F5.6 ED Features
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.
