Designed to deliver the ultimate in performance on full-frame digital SLRs, Sigma DG lenses also bring out the best in 35mm SLR film cameras and APS-C size DLSRs.
In order to attain the highest quality images, the APO lens has been made using special low-dispersion (SLD) glass and is designed to minimize color aberration.
This lens uses a motor driven by ultrasonic waves to provide a quiet, high-speed AF.
To ensure stability in focusing, this lens moves the inner lens group(s) without changing the lens' physical length.
This lens can be used with the APO Teleconverter EX. It can increase the focal length and will interface with the camera's AE (automatic exposure) function.
The exterior of this lens is EX-finished to denote the superior build and optical quality, and to enhance its appearance.
