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

maneuverability.

​

​

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.
