Technology
All figures calculated by SIGMA SA mount.
Appearance and specifications are subject to change without notice.
* Vignetting will occur if the lens is used with image sensor larger than APS-C size or 35mm SLR, and APS Film SLR cameras. To find the 35 mm camera equivalent focal length, multiply the DC lens focal length by the “crop factor” (digital multiplier) of 1.5~1.7, depending on the brand of DSLR camera on which the lens will be used.
