Photography is your passion. Sigma’s passion is creating world-class cameras and lenses that offer a total solution for every photographer. Whether you need the versatility of a professional DSLR, the portability of a compact camera equipped with a professional-grade sensor, or an expansive range of high-fidelity precision optics, Sigma provides a complete system to handle any photographic challenge.

Stability When You Need It
Sigma’s OS (Optical Stabilizer) technology dramatically expands photographic possibilities by reducing the effects of camera movement when shooting handheld. The OS system uses two sensors inside the lens to detect vertical and horizontal movement of the camera, and works by moving an optical image-stabilizing lens group to effectively compensate for camera shake. The OS function offers the equivalent to using a shutter speed 4 stops faster, and provides precise compensation for camera shake throughout the entire zoom range—a huge advantage for lenses like the 18-250mm ƒ/3.5-6.3 DC OS HSM.

“F” Low Dispersion (FLD) glass
“F” Low Dispersion (FLD) glass has been adopted and used in Sigma’s new, high-performance lenses. FLD glass is the highest-level, low-dispersion glass available with extremely high-light transmission. With a performance equal to fluorite glass, this optical glass has a low refractive index and low dispersion compared to current optical glass. It also benefits from high anomalous dispersion. These characteristics offer excellent correction for residual chromatic aberration (secondary spectrum), which cannot be corrected by ordinary optical glass and ensures high-definition and high-contrast images. FLD glass offers superior optical performance, equal to fluorite, at an affordable price. The density of FLD glass is lower than traditional optical glass, ensuring a lighter construction of large-aperture lenses.

FLD glass has been incorporated into three recently announced lenses. Four elements have been included in the Sigma 8-16mm ƒ/4.5-5.6 DC HSM, and two elements have been included in both the Sigma APO 70-200mm ƒ/2.8 EX DG OS HSM and the Sigma 17-50mm ƒ/2.8 EX DC OS HSM.

SD15: Unparalleled DSLR Performance
The newest model in Sigma’s venerable line of professional DSLRs, the SD15 is powered by the 14-megapixel Foveon X3 direct image sensor, which can capture all primary RGB colors at each and every pixel location, arranged in three layers. The new SD15 incorporates the “TRUE II” image-processing engine which processes the large amount of data from the 14-megapixel direct image sensor.

It also provides high-resolution power and reproduces high-definition images with impressive three-dimensional detail, rich in gradation. Built to perform flawlessly for years, the durable shutter mechanism, which has a life of over 100,000 actuations, is designed to meet the needs of the most demanding photographers.

DP SERIES: Professional Quality To Go
Sometimes you need to travel light, without sacrificing image quality. Sigma’s DP Series cameras have the power of Foveon sensor technology—the same technology used in Sigma’s professional DSLRs—in a compact form factor that’s ideal for candid and travel photography, or any occasion when a DSLR is impractical. Despite being small enough to carry anywhere, the DP Series delivers picture quality high enough to print beautifully in large sizes. The latest versions, the DP1x and DP2s, remain true to the original DP Series and maintain their wide-focal-length lens, but reflect several exciting upgrades. With a new rear design, the new "True II" image-processing engine and the latest RAW-image-processing software, the DP1x and DP2s are full-spec digital cameras with all the power of a DSLR.

Sigma has refined optical technology and design to fully realize the possibilities of digital photography and offer photographers capabilities they won’t find elsewhere.

Every Sigma lens delivers optimum optical quality and smooth handling characteristics through a combination of uncompromising design and advanced technology. Sigma’s precision engineering results in exceedingly dependable, world-class performance, so you can focus on the art of great image making.
