DSLR camera. Offering a bright F1.4 aperture and an angle of view extremely
close to that of human vision, this lens is ideal for many different types of pho-
tographic expression. Featuring an advanced design and the latest manufac-
turing technologies, this lens delivers highest-level image quality worthy of the
Art line. The photographer can leverage the shallow depth of  eld for a beauti-
ful bokeh effect in snapshots, portraits, landscapes, and many other types of

F1.8 brightness throughout the zoom range—large-aperature
standard zoom lens for APS-C format cameras
SIGMA 18-35mm F1.8 DC HSM is the  rst 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 cameras with APS-C size sensors. The
lens has a focal range equivalent to 27-52.5mm in a 35mm format, and it can
cover the angles of view of multiple  xed-focal length lenses. This wide-aperture,
standard zoom lens enables the photographer to expand creative possibilities on
any occasion.

SIGMA’s second APS-C format zoom lens offering F1.8 throughout
the zoom range
While offering even greater brightness than a F2.8 telephoto zoom, this lens cov-
ers the focal lengths of three prime lenses in one package: 85mm F1.8, 105mm
F1.8, and 135 mm F1.8 (35mm equivalent). A true game-changer, this lens is
ideal for portraits with subtle bokeh effects and more, and it sets a new standard
for zoom lens image quality. By including one or more low-dispersion element in
every element group, this lens ensures outstanding image quality throughout the
zoom and focal range. Thanks to SIGMA’s inner focus and inner zoom technolo-
gies, adjusting the focus and zoom rings does not change the length of the lens,
and turning the zoom ring is not prone to cause focus shift.

Case and cover lens cap (LC907-01) included
The world’s  rst* F1.4 ultra-wide-angle lens for full-frame DSLRs
With a focal length of 20mm and F1.4 aperture, this lens delivers outstanding
large-aperture brightness and bokeh, delivering unprecedented visual experi-
ences. Allowing the photographer to leverage the perspective provided by the
wide angle and the shallow depth of  eld provided by the large aperture, this
lens is ideal not only for such subjects as landscapes and starry skies, but also
for snapshots in low light, indoor photography, portraits with a natural bokeh
effect, and much more.

From our Art line—F1.4 large-diameter wide-angle lens with
best-in-class optical performance
This lens in the culmination of our experience designing wide-angle lenses, our
design know-how nurtured through crafting the lenses in our Art line, and all of
our manufacturing expertise. The result is high-resolution, outstanding image
quality from the center of the image to the edges. While delivering high resolu-
tion of the part of the subject that is in focus, this lens also offers an attractive
bokeh effect. Even at wide-open aperture, the image quality is extremely  ne
without streaking. FLD and SLD glass elements minimize transverse chromatic
aberration, which can be most noticeable at the edges of an image. Optimized
lens power distribution helps minimize axial chromatic aberration as well.
Combined, these features deliver exceptionally sharp, high-contrast image
quality without color bleeding throughout the entire image.

Our Art line  agship—large-aperture wide-angle lens with F1.4
brightness
With unsurpassed expressive performance, this large-aperture lens offers a
bright F-number of F1.4 in wide-angle photography and beautiful bokeh ef-
fects. Coma of point light sources is minimized, making this lens an excellent
choice for photographing illumination. The aspheric lens at the front of the lens
series helps minimize both distortion and vignetting. The view nder image is
bright from the center to the edges, and the rounded diaphragm produces an
attractive round bokeh effect at large-aperture settings.
