This compact, large and constant F2.8 aperture zoom lens and is ideal
for digital SLR cameras. Two SLD elements and four aspherical lenses provide
the ultimate correction against distortion as well as all types of aberration,
especially spherical aberration. Its advanced optical design ensures high
performance throughout the entire zoom range.
The use of aspherical lenses in the construction of this lens not only
corrects aberrations but also produces a very small and lightweight lens
design. Its compact, yet robust, construction has an overall length of
87.2mm, maximum diameter of 74mm, filter size of diameter 67mm and weight
of 510g.

This lens offers a large aperture of F2.8 over its entire range of focal
lengths and its large depth of field offers greater freedom of creative
expression. This lens is perfectly suited for low light conditions indoors or at dusk.
It covers wide angle to medium telephoto and is ideally suited to a wide
range of subjects.
Two Special Low Dispersion (SLD) glass elements are provided for effective
compensation of color aberration, which is a common problem with super-wide
angle lenses. Four pieces of hybrid aspherical lenses offer excellent
correction for distortion as well as all types of aberration. This lens’
excellent optical performance makes it an ideal lens for Digital SLR Cameras
as well as film SLR cameras.
It incorporates "Super Multi Layer Coating" to reduce the influence
of harmful light caused by reflections from the digital image sensor.
It has a minimum focusing distance of 33cm at all focal lengths and a
maximum magnification ratio of 1:4.4, which is very convenient for close-up
photography.
This lens is also equipped with a zoom lock that eliminates "Zoom
Creep". This remarkably compact, high performance zoom lens is ideally
suited for traveling.
Since the front of the lens does not rotate, a Petal-type hood and circular
polarizing filters can be easily used.
