Sigma has released MC-11 Mount Converter Firmware Update 1.02 (Download Here) that adds support for Sigma 12-24mm F4 DG HSM Art, 85mm F1.4 DG HSM Art and 500mm F4 DG OS HSM Sports lenses.

Sigma MC-11 Mount Converter Firmware Update 1.02 Improvements:

• It is fully functional with Sigma 12-24mm F4 DG HSM Art, Sigma 500mm F4 DG OS HSM Sports and Sigma 85mm F1.4 DG HSM Art lenses.

• It has reduced the startup time between turning on the camera and taking an image by not initially driving the focus when the camera is turned on.

• When lenses with Optical Stabilizer (OS) function that are not fully compatible with Sigma Mount Converter MC-11 are attached with Sigma Mount Converter MC-11 and mounted on a camera which incorporates a stabilizer unit, it enables the camera’s stabilizer unit to be turned off and the lens’s OS function to be turned on and off.

• It has improved the AF accuracy of Canon EF lenses that are not fully compatible with Sigma Mount Converter MC-11.

• It has corrected the phenomenon where the distortion correction figure is not indicated properly in the camera, when Sigma 24-105mm F4 DG OS HSM Art is attached.
