Large
aperture standard zoom lens designed specially for digital SLR cameras.
The
lens is ideally suited for a wide variety of subjects and is designed
specifically for digital SLR cameras featuring APS-C size image sensors.
The Nikon fit version also includes an HSM auto focus motor.
This revolutionary lens has a minimum focusing distance of 20cm (7.9”)
throughout the entire zoom range. A maximum magnification of 1:2.3 enables
extreme close-up photography. An impressive achievement for a standard
zoom lens.
The new lens design and multi-layer lens coating reduce flare and ghosting,
a common problem with digital cameras.
A Special Low Dispersion (SLD) lens and two aspherical lens elements provide
excellent correction for all types of aberrations and produce a high level
of optical performance throughout the entire zoom range.
This lens offers
a large F2.8 aperture at 17mm wide angle and yet it is compact, with an
overall length of just 82.5mm (3.2”) and diameter of 79mm (3.1”). Performance
is superb, even in relatively low light conditions indoors or at dusk.
The lens is equipped with an inner focusing system, which prevents the
front element from rotating making it particularly suitable for petal
shaped hoods and circular polarizing filters.
The lens is also equipped with a zoom lock that eliminates 'zoom creep'
during transit.
