From Sigma:
The SIGMA Corporation is pleased to announce the release of its lens firmware version 2.00 for its SIGMA GLOBAL VISION (SGV) interchangeable lenses compatible with Canon digital cameras featuring Lens Aberration Correction. The three types of corrective functions available are for peripheral illumination, chromatic aberrations, and distortion.
By updating their lens firmware to version 2.00, customers with compatible SGV interchangeable lenses for Canon cameras can perform aberration corrections that match the optical characteristics of their lenses. In addition, by turning Lens Aberration Correction on and before taking photographs, users can prevent certain image and operation errors from occurring.
