Sigma Working on MC-11 Firmware Fix For Sony a9

Translated Release:
For customers using Sony “α9 (ILCE-9)”

Thank you very much for your continued support of Sigma products.

This time, in the combination of our MOUNT CONVERTER MC – 11 (SA – E, EF – E) and some zoom lenses to “α 9 (ILCE – 9)” which was released from Sony Corporation on May 26 , It turned out that the phenomenon that the in-focus mark lights up occurs even if the subject is rarely in focus when taking pictures at the telephoto side with AF-S.

We deeply apologize for any inconvenience to our favorite customers.

We are currently conducting investigations. If the cause is found out, we will inform you again on our website.

We sincerely look forward to your company and our products.
