Optimized for DSLRs with APS-C size image sensors, Sigma DC lenses leverage original technology fostered in the development of Sigma SD series cameras. The configuration of lens elements and the lens coatings represent the culmination of decades of optical engineering experience. The result is truly excellent performance in a compact, lightweight format that offers outstanding flexibility to the serious photographer.

*DC lenses have an image circle that covers APS-C size image sensors. Not for use on digital cameras having image sensors larger than APS-C size or on 35 mm or APS film cameras, as vignetting will occur. 
* To find the 35 mm camera equivalent focal length, multiply the DC lens focal length by the “crop factor” (digital multiplier) of 1.5, 1.6 or 1.7, depending on the brand of DSLR camera on which the lens will be used. To find which DC lens is equivalent to a full frame lens, divide the focal length of the full frame lens by the same crop factor.

Designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35 mm SLR film cameras and APS-C size DSLRs. Remarkable image rendition is achieved by comprehensive correction of aberrations and distortions. Special care was taken to thoroughly minimize color fringing caused by lateral chromatic aberration which is particularly noticeable at high resolution in digital photography. DG lenses can offer both high contrast and subtle tonal gradations, unmarred by flare and ghosting, thanks to Sigma's digitally-optimized optical design and original Super Multi-Layer Coating technology which suppress reflections between image sensor and lens surfaces. Large image circles assure ample peripheral illumination to prevent vignetting.

High-performance lenses, designed exclusively for mirrorless interchangeable lens cameras. The latest technology for the lens design ensures high optical performance, a compact construction and quiet autofocusing. The superior telecentricity assures sharp and high resolution image quality across the entire image plane.


Sigma’s professional-grade prime lenses and wide-aperture zoom lenses that maintain their maximum f-stop regardless of zoom position

An optical stabilizer mechanism built into the lens helps assure a sharp image while giving you freedom of movement and more latitude in camera settings.

To increase stability, this lens configuration uses movable internal lens elements that adjust focus without changing the length of the lens barrel.

Aspherical lenses offer greater design latitude, raise performance, permit use of fewer lens elements and allow a more compact size.

Using a motor driven by ultrasonic waves, these lenses offer speedy auto focusing and quiet operation.

This indicates a lens that will accept available Sigma APO Teleconverter attachments, which increase focal length and support AE (automatic exposure) operation.

Sigma’s top-of-the-line telephoto lenses use at least two elements of ELD, FLD, SLD or other low-dispersion glass to deliver impeccable image quality unsullied by chromatic aberration.

Locating the focusing elements in the rear portion of the lens contributes to faster auto focusing and reduced noise.
