The artist’s camera
High-performance Sigma lenses.
Founded in 1961 as a lens
manufacturer, Sigma has leveraged
its original technologies to create
unique products and assume its
position as a leading photographic
equipment provider,
despite a relatively late
start in the marketplace.
Today, Sigma continues
to be a leader in the
highly competitive
interchangeable lens
market, thanks to its
dedication to ongoing
development of innovative
products and an unstinting
approach to quality control.
Today the standard for SLR
cameras, the rear converter
was originally a Sigma
invention. In the past, a
conversion lens could
only be used with a single
objective lens. In addition,
the conversion lens came
between the objective
lens and the body, making
the camera front-heavy.
Sigma's innovation solved
these issues, leading to the
user-friendly lens system
with which photographers
are familiar today.
A lens lineup designed for
highest image quality.
Leveraging advanced optical
design and precision manufacturing
expertise, Sigma has developed
for its SA mount lenses a flare- and
ghost-reducing super multi-layer
coating, HSM (Hyper Sonic Motor),
the OS (Optical Stabilizer) anti-shake
compensation function,
ELD (Extraordinary Low Dispersion)
and SLD (Special Low Dispersion)
glass, aspheric elements, and other
cutting-edge components
and features. All Sigma
standard, wide-angle,
telephoto, macro, fisheye,
and other lenses are
designed to make best use
of the exceptional image
quality of the SD15.
Seeking always to help
photographers achieve
the best results possible
while enjoying the full
delight of photography,
Sigma currently produces
more than 40 different
types of lenses, as well
as camera bodies that
support lens function at the
highest level.
Developed and
manufactured to meet the
highest standards in the
industry, Sigma's SA Mount
lenses offer photographers
the selection and reliable,
responsive performance
that make true creativity
possible.
