SIGMA MC-11 EF-E Mount Converter Firmware 1.11

Changes:

- It has corrected the phenomenon which may occur with the combination of SIGMA MOUNT CONVERTER MC-11 and some of SIGMA’s interchangeable zoom lenses on Sony a9 (ILCE-9) that when using AF-S mode and shooting in telephoto range, it could occasionally display the shot as in focus, although it may not be correctly locked on the subject.
- It has become compatible with the SIGMA 24-70mm F2.8 DG OS HSM | Art for CANON (Firmware Ver.1.02), as well as the SIGMA 100-400mm F5-6.3 DG OS HSM | Contemporary for CANON (Firmware Ver1.03).

Before Updating:

- Use a fully charged battery or connect the camera to the AC adapter.
- Do not disconnect the battery or the AC adapter during the firmware update of the lens.
- Ensure the power of the camera is always kept ON during the firmware update of the lens.
- The lens needs to be attached to a camera to update the firmware.

About Lens Updates:

Upgrading or downgrading your lens to a different firmware version might enhance the unit's overall performance and stability, and could also improve some of the lenses' features (a good example would be faster autofocus speed).

In order to apply a firmware properly, other than the one already installed, you should check that the lenses are connected to the camera body, copy the compatible update on a memory card, and insert it into the camera.

From the device's menu, browse to the Firmware Upgrade section, and enable the new firmware. Since each device has various ways to enter the update mode and particular steps that should be taken for a successful upgrade, you must make sure that you read the product's installation guide.
