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.
