At the heart of photography
Ever since Sigma’s founding,
we have always believed that a photo
is only as good as the lens. It follows
that choosing a new lens opens up
fresh possibilities for photographic
expression. This philosophy has
inspired Sigma’s quest for
lens system perfection throughout
our 50-year history.
Today, Sigma’s unique line of products
has won the acclaim of sophisticated
photo enthusiasts around the world,
reflecting the technological mastery
and rich experience that goes into each
and every lens. It is a direct result of our
dedication to photographic excellence
meshing with the photographer’s
desire to capture the perfect shot.
More options for
more photographers
Given a wide variety of optically
superior lenses, the photographer can
select the one that will best achieve
a particular goal. A broad range of
lenses also stimulates photographic
creativity. This is why we want to
give freedom of choice — and the
expressive potential it brings — to
as many photographers as we can.
Our products employ innovative
technology to provide solutions to the
issues faced by every photographer
with a strong creative urge.
Tools of inspiration
and imagination
At times we have ventured to introduce
products for which there was no
precedent. Many of these world’s firsts,
we are proud to say, have revealed new
dimensions for photographic exploration
and contributed to the very culture of
photography.
Take the wide-angle zoom lens for
example. In the field of mountain
photography, devotees were quick to
applaud Sigma’s innovative compact and
lightweight wide-angle zoom lenses which
greatly expanded focal-length options
under the most challenging conditions.
Today the wide-angle zoom has become
a well established category in its own
right. But at the time, “wide angle”
meant a prime lens, and nobody even
considered the need for variable
focal length. That Sigma saw things
differently and had the technology to
create a new genre is a true reflection of
our inventive spirit regarding the tools
of photography.
Pioneering tomorrow’s lens technology
Photographs can express intensely
personal visual experiences as seen
by the mind’s eye. At Sigma we seek
to respond to the diverse demands of
photographers who are bewitched by
the photographic medium’s rich trove
of creative possibilities. This is why our
product development and R&D efforts
are based on a policy of in-house
development for the key technologies
that we consider most important.
For our lenses, we not only design
the optics and mechanisms, but also
the firmware, electronic circuits and
systems, and even the high-precision
molds. From the smallest screw
to the completed product, Sigma
uses a comprehensive integrated
manufacturing system to deliver state-
of-the-art products of the highest
quality to markets around the world.
Furthermore, our speedy and flexible
small-lot production lines let us
satisfy real user needs with solutions
developed from unique vantage points.
Supported by this highly adaptable
system, Sigma’s unconventional
manufacturing approach focuses on
continuous improvement of advanced
processing and fabrication technology,
while creating greater freedom of design
through novel solutions to challenging
optics issues.
Our goal is to give form to the
photographer’s imagination by
developing tools that bring images to
life. When we are successful, the result
can be an awe-inspiring experience for
both the creator and the viewer. However
much photographic technology may
evolve, Sigma’s starting point remains
unchanging. In the final analysis, it’s all
about creating great photographs.
