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.
SIGMA DC LENS*1 *2
High-performance lenses for cameras with APS-C sensors
These lenses are designed especially for cameras with APS-C sensors. The smaller image
size makes possible a compact, lightweight format that offers outstanding flexibility and
SIGMA DG LENS
High-performance lenses for cameras with full-frame sensors
Designed to deliver the ultimate in performance on cameras with full-frame sensors,
these lenses also bring out the best from APS-C sensor cameras.
SIGMA DN LENS*2
High-performance lenses for mirrorless interchangeable lens cameras
These lenses are designed for exceptional performance on mirrorless interchangeable lens
cameras with a short flange back distance.
*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 film cameras, as vignetting will occur.
*2: To find the 35mm 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.
