Product Description
-------------------
SIGMA 18-35mm F1.8 DC HSM is the first zoom lens ever to achieve
a maximum aperture of f1.8 throughout the zoom range. It is a
wide aperture, standard zoom-lens for digital single lens reflex
camera's with APS-C size sensor's. The lens has a focal range
equivalent to 27mm - 52.5mm in a 35mm format and it can cover the
angles of view of multiple fixed focal length lenses. This wide
aperture, standard zoom lens enables the photographer to expand
creative possibilities on any occasion.
Our Art line delivers high-level artistic quality Sigma is
organizing all its interchangeable lenses into three product
lines; Contemporary, Art and Sports. Designed with a focus on
sophisticated optical performance and abundant expressive power,
our Art line delivers high-level artistic expression. Developed
with the maximum emphasis on artistic touch, they are designed to
meet the expectations of users who value a creative, dramatic
outcome above compactness and multifunction. Along with
landscapes, portraits, still-life, close-up and casual snaps,
they are perfect for the kind of photography that unleashes the
inner artist. Ideal for studio photography, they offer just as
much expressive when capturing architecture, starry skies,
underwater s and many other scenes.
Excellent Usability A zoom lens is very convenient as it offers
various angles of view just by rotating the zoom ring. However,
the down side was that no zoom lens ever offered a faster
aperture than f2.8 which led photographers to select fixed focal
length lenses for brighter images. While the aperture value of
prime lenses is superior to zoom lenses, their field of view is
always the same, and therefore it was always necessary to carry
many fixed focal length lenses. SIGMA 18-35mm F1.8 DC HSM is a
new generation lens that can deliver images at f1.8 aperture
throughout its focal length. The bright viewfinder is very
helpful for checking the focus and composition of the image. If
it is compared with a lens of F2.8, the faster shutter speed and
the shallow depth of field of F1.8 further expands creativity.
From wide to standard range this lens offers the excellent
versatility and performance of multiple fixed focal length
lenses.
Designed to minimize flare and ghosting Flare and ghosting were
thoroughly measured and monitored from an early stage in the
lenses development to establish an optical design which is
resistant to strong incidental light such as backlight. The Super
Multi-Layer Coating reduces flare and ghosting and provides sharp
and high contrast images even in backlit conditions. Attaching
the matched petal type hood, which is supplied, will provide
extra protection from flare and ghosting.
Minimum focusing distance of 28cm With a minimum focusing
distance of 28cm and a maximum magnification ratio of 1:4.3, this
lens is excellent for close-up photography.
Hyper Sonic Motor The HSM (Hyper Sonic Motor) ensures a silent,
high-speed AF function. Optimizing AF algorithm, smoother AF is
achieved. It also enables full-time manual focusing capability
which allows sensible focus adjustment by simply rotating the
focus ring.
Incorporating Rounded diaphragm The 9 blade rounded diaphragm
creates an attractive round bokeh at large-aperture settings.
Design concept The new product lines incorporate rubber for the
attachment part of the provided lens hood. For better usability,
the designs of the lens cap and AF/MF changeover switch have been
improved. In order to ensure high accuracy of the product, all
metallic parts and the new compound material, TSC (Thermally
Stable Composite), which has a high affinity to metal parts, are
housed internally. On the lens barrel, the last three digits of
its release year are engraved so the lens can be identified
according to the year of its launch.
To use USB Dock: Please attach a USB Dock to your lens'
part, just like you attach your camera to the lens. Please use
the supplied USB Cable and connect to a computer which has the
dedicated software “SIGMA Optimization Pro” installed. For
further information on how to operate the product, please refer
instruction manual of “SIGMA Optimization Pro”.
