ESSENTIALS

You

ll find our philosophy and craftsmanship in every product

Our lineup fully expresses our approach to lenses and photography itself. All of our lenses belong to one of three

product lines—Art, Contemporary, or Sports—all of which share our development philosophy and advanced manu-

facturing system. High performance, high quality, and high end in every respect, these lenses give people who love

photography and choose SIGMA products lasting value and consistent, exciting results. The secret is our passion

for craftsmanship that we put into every production process and every product.

QUALITY

Inspecting each and every lens with our proprietary MTF measuring system,

we deliver premium quality

There are three requirements for outstanding lenses: ne design, precise manufac-

turing and inspection that ensures compliance with all specications. SIGMA lenses

are born of outstanding design concepts and excellent manufacturing technology.

But they’re not complete until they undergo our uncompromising lens performance

evaluation. We've developed our own proprietary MTF (Modulation Transfer Function)

measuring system. We check each and every lens in our product lines before we ship

it, in order to always deliver lenses with ultra-high-performance and quality.

CRAFTSMANSHIP

Producing everything in Aizu for “Made in Japan” quality

Apart from a handful of processes, we perform all manufacturing in house at our Aizu

factory in Fukushima Prefecture. This includes grinding lenses, molding plastic parts,

painting, mounting substrates, assembly, manufacturing screws and other parts, and

machining molds. Thanks to this integrated production system, we are now one of the

very few manufacturers whose products are truly “Made in Japan.“ With its clean air

and water and focused, hard-working people, Aizu offers an optical equipment man-

ufacturer the perfect operating environment and conditions.

We pride ourselves on the authentic quality of SIGMA products, born of a marriage

between highly attuned expertise and intelligent, advanced technology. Our sophis-

ticated products have satised professionals and lovers of photography all over the

world, because our manufacturing is based on genuine craftsmanship, underpinned

by the passion and pride of all staff at our Aizu factory.
