This
Ultra wide-angle zoom lens has a maximum aperture of F3.5 throughout the
entire zoom range, making it suitable for low-light and indoor photography.
It’s wide-angle of view from 102.4 degrees produces striking images
with exaggerated perspective, enabling photographers to emphasise the
subject. ELD (Extraordinary Low Dispersion) glass, SLD (Special Low Dispersion)
glass and Aspherical lenses provide excellent correction of all types
of aberrations. The Super Multi-Layer lens coating reduces flare and ghosting
and creates high image quality throughout the entire zoom range. The HSM
(Hyper Sonic Motor) ensures fast and quiet autofocus, while allowing full-time
manual focus override.
Ultra
wide-angle zoom from 102.4* degrees
The 10-20mm F3.5 EX DC HSM lens offers photographers greater freedom of
expression by rotating the zoom ring. It is a very powerful tool for architectural,
indoor and landscape photography.
* The angle of view changes depending on which camera model
the lens is attached to.
Exaggerated
perspective
This ultra wide-angle lens allows photographers to create an exaggerated
perspective between the subject and the background to emphasise, for example,
expanses of a landscape.
Large F3.5 aperture through the entire zoom range
The large, constant aperture of F3.5 provides a bright image in the viewfinder,
which helps photographers easily check focusing and composition.
Superior image quality
One SLD (Special Low Dispersion) and two ELD (Extraordinary Low Dispersion)
glass elements are employed for effective compensation of colour aberration.
The use of two glass mold and two hybrid aspherical lenses offer excellent
correction for distortion and astigmatism and ensure superior image quality.
The Super Multi-Layer coating reduces flare and ghosting and provides
high contrast images throughout the entire zoom range.
Quiet and fast AF
This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet
and high-speed auto focus as well as full-time manual focus override by
rotation of the focus ring.*
* AF will not function with Pentax ist* series and K100D
DSLR cameras that do not support HSM.
Petal-type Hood
An inner focusing system eliminates front lens rotation, making the lens
particularly suitable for using the included petal-type lens hood which
blocks out extraneous light.
Minimum
focusing distance of 24cm (9.4") at all focal lengths
This lens has a minimum focusing distance of 24cm (9.4 inches) throughout
the entire zoom range. This close focusing distance on such a wide-angle
lens emphasises perspective and allows the photographer to capture high
quality images, not only of the foreground subject but also the surrounding
scenery.
* Vignetting
will occur if the lens is used with digital cameras with image sensors
larger than APS-C size or 35mm SLR cameras.
