Product Description
Large aperture standard zoom lens designed for digital SLR cameras.
This large aperture standard zoom lens offers an aperture of F2.8 at the
17mm focal length and is ideal for many situations such as portraits, sports,
macro and general photography. The OS (Optical Stabilizer) function offers the
use of shutter speeds approximately 4 stops slower than would otherwise be
possible. For Sony and Pentax mount, the built-in OS function of this lens can
be used even if the camera body is equipped with an anti-shake function. As the
compensation for camera shake is visible in the view finder, the photographer
can easily check for accurate focus and ensure there is no subject movement. The
maximum aperture of F2.8 produces an attractive background blur and improves
autofocus speed.
This lens has a minimum focusing distance of 22cm (8.6 inches) throughout the
entire zoom range and maximum magnification ratio of 1:2.7, making it ideal for
close-up photography. It is possible to focus as close as approximately 4.7cm
from the tip of the lens to the subject making this lens particularly useful for
close-up photography.
Three aspherical lenses and one ELD (Extraordinary Low Dispersion) glass element
provide excellent correction for all types of aberrations. High image quality is
assured throughout the entire zoom range. The Super Multi-Layer Coating reduces
flare and ghosting and provides high contrast images. The incorporation of HSM
(Hyper Sonic Motor) ensures a quiet and high speed AF. This lens has a rounded 7
blade diaphragm which creates an attractive blur to the out of focus areas of
the image. The inner focusing system eliminates front lens rotation, making the
lens particularly suitable for using the supplied petal-type lens hood and
circular polarizing filters.
