ABOUT OUR LENS
Note 1: 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 35mm or APS lm cameras, as vignetting will occur.
Note 2: To nd the 35mm camera-equivalent focal length, multiply the DC lens focal length by the crop factor (digital multiplier) of 1.5-2, depending on the brand of DSLR camera on which the lens will be used. To
nd which DC lens is equivalent to a full-frame lens, divide the focal length of the full frame lens by the same crop factor.
One SIGMA—Three product lines
We reorganize all of our interchangeable lenses into three product lines. Each line has its own clearly dened concept,
and we develop each lens to exemplify the concept of one of the lines.
Lens categories for all major standards
For our three new lines, Sigma develops lenses optimized for 35mm full-frame, APS-C,
and mirrorless interchangeable lens cameras.
