ABOUT OUR LENS
Note 1: DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having
image sensors larger than APS-C size or on 35mm or APS film cameras, as vignetting will occur.
Note2:Tofind the35mmcamera-equivalent focal length,multiply theDC lens focal lengthby thecrop factor (digital
multiplier) of 1.5, 1.6, or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which
DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.
One Sigma
Three product lines
We reorganize all of our interchangeable lenses into three product lines. Each line has its own clearly defined concept,
and we develop each lens to exemplify the concept of one of the lines.
Lens categories for all major standards
For our three new lines, Sigma develops lenses optimized for 35mm full-frame, APS-C,
and mirrorless interchangeable lens cameras.
SIGMA DN LENS
High-performance lenses for mirrorless
interchangeable lens cameras
We have developed these high-performance,
compact lenses with quiet autofocusing based on
original technology and know-how we acquired
through the development of digital cameras and
interchangeable lenses. The superior telecentricity
assures sharp and high-resolution image quality
across the entire image plane. In addition, DN lens-
es benefit from a linear AF motor which moves the
lens unit directly without the need for gears or other
mechanical parts. This system ensures accurate and
quiet autofocusing, making the lens suitable for vid-
eo recording as well as still photos.
SIGMA DC LENS
High-performance Lens
for APS-C format DSLR cameras.
Optimized for DSLRs with APS-C size image sensors,
these lenses leverage original technology fostered
in the development of Sigma SD series cameras. The
configuration of lens elements and the lens coatings
represent the culmination of decades of optical engi-
neering experience. The result is truly excellent per-
formance in a compact, lightweight format that offers
outstanding flexibility to the serious photographer.
SIGMA DG LENS
High-performance SLR lenses with full-frame
sensor coverage
Designed to deliver the ultimate in performance on
full-frame digital SLRs, Sigma DG lenses also bring
out the best in 35mm SLR film cameras and APS-C
size DSLRs. Remarkable image rendition is achieved
by comprehensive correction of aberrations and
distortions. Special care is taken to thoroughly
minimize color fringing caused by lateral chromatic
aberration, which is particularly noticeable at high
resolution in digital photography. DG lenses can
offer both high contrast and subtle tonal gradations,
unmarred by flare and ghosting, thanks to Sigma's
digitally optimized optical design and original Super
Multi-Layer Coating technology, which suppress
reflections between image sensor and lens surfaces.
Large image circles assure ample peripheral bright-
ness to prevent vignetting.
Incorporating the very latest technology in these
lenses, Sigma has solved the difficult problem of
keeping size and weight low without compromis-
ing on advanced optical performance or utility.
High-performance, versatile, compact and superbly
portable, the lenses in our Contemporary line can
handle landscape shots on your travels, casual
snapshots, family pictures, and all sorts of other
photo opportunities.
With unsurpassed expressive performance, these
lenses meet the highest standards demanded by
photographers. Developed with the maximum em-
phasis on artistic touch, our Art line lenses are de-
signed 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're perfect
for the kind of photography that unleashes the inner
artist. Ideal for studio photography, they offer just
as much expressive scope when capturing architec-
ture, starry skies, underwater shots and many other
scenes.
With their high-level optical performance and ex-
pressive power, these lenses can capture fast-mov-
ing subjects, even at distance. This high-perfor-
mance line also offers a variety of functions to aid
the photographer in challenging conditions and
scenarios. Besides sports photography, the lenses
are also perfect for nature shots featuring birds,
wild animals and other creatures, and for capture of
aircraft, trains, race cars and more. Our Sports line
lenses also offer a wide range of customization func-
tions: exclusive software allows many settings to be
customized.
