The single-lens reflex camera of choice

The most complete system 
camera available

To the photographer, exciting new 
subjects and compositions constantly 
appear—and drive the demand for a 
versatile camera that can grasp these 
opportunities. The most complete 
and flexible system camera available 
is the single-lens reflex (SLR) camera.

Refined by photographers over many 
decades, SLR technology allows the 
photographer to create a genuinely 
personalized system that matches his 
or her own style—a benefit offered 
by no other type of camera. Wide-
angle, standard, telephoto, macro, 
high ratio zoom—all of these lenses 
and a wide range of accessories 
are available, accommodating any 
photographic circumstance.

The photographer's vision 
makes the camera.

Since the image the photographer 
has in mind is highly individual, 
Sigma believes a good camera 
should allow creativity to come to 
the fore, helping the photographer 
overcome limitations and expand the 
possibilities of the craft. No camera 
affords the photographer more 
freedom than a digital SLR. 

First comes the desire to create an 
image and capture meaning. Next 
come the proper tools—a digital 

SLR camera, lenses, and accessories 
suited to the photographer's unique 
vision. To take the perfect picture, 
the photographer needs to be able to 
move freely from instant to instant. 
More than any other system, a digital 
SLR camera helps the photographer 
be creative and take advantage of 
moments that only come once.

The appeal of an optical viewfinder

Another critical part of a digital 
SLR camera is the optical 
viewfinder. Based on advanced 
digital technology, the backlit LCD 
viewfinders with live preview 
and electronic viewfinders (EVF) 
found in compact digital cameras 
offer a high degree of scene 
visibility and convenience.

An optical viewfinder offers many 
distinct advantages. Verification of 
every aspect of the scene with the 
naked eye. High-precision focusing. 
A real-time and realistic image 
of the subject. Finer detail. Finer 
photographs.

An electronic image simply can't 
imitate these things, yet they are all 
crucial in taking highly precise, 
highly individual photographs. 
Currently, nothing matches an optical 
finder for revealing the subject exactly 
as it is and inspiring the photographer 
to take the ideal picture as conceived 
by that person.

A camera that celebrates the 
photographer's style

In the sleek, sophisticated body 
of a Sigma digital SLR is the finest 
image sensor available. It is coupled 
with a Sigma lens that offers 
crystal-clear images and the highest 
level of finished image quality. 
The optical viewfinder satisfies the 
professional eye and makes taking 
pictures truly a delight. In addition, 
a Sigma digital SLR camera 
coordinates well with accessories 
to enhance the enjoyment of every 
photographic opportunity. 

In short, a Sigma SLR camera 
is the complete system camera 
that empowers the photographer 
in the widest variety of creative 
circumstances. It allows the 
photographer not only to respond 
to the scene that presents itself but 
also to find and express a uniquely 
personal photographic method, 
style, and spirit.

More than any other camera, the 
Sigma digital SLR camera has 
the individuality to support the 
creativity of the photographer 
and maximize his or her abilities. 
It is a resource that sharpens 
discernment, deepens the 
compositional sense, and 
strengthens the creative will, 
allowing the photographer to 
take artistic action.
