Corresponding AF Mounts
SIGMA / SONY / NIKON / PENTAX / CANONVignetting 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, 1.6 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.
Sony and Pentax mounts are not incorporated with OS function.
AF will not function with Pentax ist* series and K100D DSLR cameras that do not support HSM.
