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 in-

spired 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 su-

perior 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 expres-

sive potential it brings — to as many

photographers as we can. Our prod-

ucts 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 prec-

edent. Many of these world’s ﬁrsts, we

are proud to say, have revealed new

dimensions for photographic explora-

tion and contributed to the very culture

of photography.

Take the wide-angle zoom lens for ex-

ample. In the ﬁeld of mountain photog-

raphy, devotees were quick to applaud

Sigma’s innovative compact and light-

weight wide-angle zoom lenses which

greatly expanded focal-length options

under the most challenging conditions.

Today the wide-angle zoom has be-

The Lens Makes the Photograph

come 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 dier-

ently 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 eorts

are based on a policy of in-house devel-

opment 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 com-

prehensive integrated manufacturing

system to deliver state-of-the-art prod-

ucts of the highest quality to markets

around the world. Furthermore, our

speedy and ﬂexible small-lot produc-

tion lines let us satisfy real user needs

with solutions developed from unique

vantage points. Supported by this

highly adaptable system, Sigma’s un-

conventional manufacturing approach

focuses on continuous improvement of

advanced processing and fabrication

technology, while creating greater free-

dom of design through novel solutions

to challenging optics issues.

Our goal is to give form to the photog-

rapher’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.
