Sigma’s MC-11 lens adapter, which allows for Canon and Sigma mount lenses to be used on Sony’s mirrorless E Mount cameras, has just received a significant firmware update. The Japanese firm, which has been riding high on the popularity of its Art Series lens lineup, is claiming the update will boost auto focus and image-stabilization performance, as well as add support for two of Sigma’s latest lenses, the 24-70mm F2.8 and 14mm F1.8. This update will make Canon mount lenses attached to a Sony mirrorless camera focus faster.

When Sigma announced its MC-11 lens adapter,  the photography industry was flooded with excitement over the possibility of an adapter that did not suffer from a big performance hit like other lens adapters on the market. Unfortunately, it did not work out as well as most hoped, and the MC-11 lens adapter did not perform much better than other options on the market upon launch. Any updates to the lens adapter will no doubt be watched closely by Canon-to-Sony camera converts hoping to get some better performance out of their old Canon-mount Sigma lenses.

Updating the firmware is a simple process. The first step is making sure that your version of Sigma Optimization Pro is updated to the latest version (1.4.1 on Windows, 1.4.0 on Mac). You can then connect the Sigma USB dock to your computer, and attach your MC-11 to the USB dock, check for updates, and follow the on-screen process to upgrade to the latest firmware — which is version 1.05.

Once that is complete, you should see the benefits of improved performance the next time you use the adapter. These performance improvements were not the only additions. Sigma also added support for some of its latest releases, such as the 14mm F1.8 DG HSM and 24-70mm F2.8 DG OS HSM.
