Sigma has updated the firmware for their MC-11 converter to version 1.12 and added support for their new SIGMA 60-600mm F4.5-6.3 DG OS HSM Sports lens, and the SIGMA 24-70mm F2.8 DG OS HSM Art lens.
Before updating the SIGMA MOUNT CONVERTER MC-11 firmware, please ensure SIGMA Optimization Pro has been updated to ver. 1.4.1 or later for Windows, and ver. 1.4.0 or later for Macintosh.
Full details can be found on Sigma’s website here.
I would love to test the new SIGMA 60-600mm F4.5-6.3 DG OS HSM Sports lens on my a9 with the MC-11. I may need to rent this lens at some point! 🙂
