Sigma released new firmware for improved Canon compatibility with several ART-series lenses. These lenses are Sigma 20mm f/1.4 DG HSM Art, Sigma 24mm f/1.4 DG HSM Art, Sigma 14mm f/1.8 DG HSM Art, SIGMA 12-24mm F4 DG HSM, SIGMA 50-100mm F1.8 DC HSM.
This firmware allows compatibility with Canon’s in-camera Lens Aberration Correction function to enable correction matching the optical characteristics of each lens. It also corrects the phenomenon that abnormal images appear or operation errors occur when the function is enabled. This firmware also corrects the phenomenon whereby the continuous shooting speed decreases in certain combinations with some cameras when used with the 14-24mm F2.8 DG HSM | Art for Canon, and the phenomenon whereby the AF speed occasionally becomes unstable when used with the 100-400mm F5-6.3 DG OS HSM | Contemporary for Canon.
For customers who own the SIGMA USB DOCK and applicable products listed below, please update the firmware via SIGMA Optimization Pro. Before updating the firmware using the SIGMA USB DOCK, please ensure to update SIGMA Optimization Pro to Ver. 1.4.1 or later for Windows, and Ver. 1.4.0 or later for Macintosh.
