Dear Tamron product users and potential purchasers.
Thank you for your interest in Tamron products. We would like to announce that we found some issues with our new lens, 28-200mm F/2.8-5.6 Di III RXD (Model A071) for SONY mirrorless cameras.
When AF-S mode, the AF operation rarely stops in the middle and the focus indicator lights up even though it is not in focus.
We are currently working on the cause of the error and expect this to be solved with a firmware update. Early June is the target date for the release of the firmware update.
Regarding the firmware updating process, please be assured that the process is accomplished directly through the SONY camera and supported by the Sony firmware updating function. As soon as the process is finalized, we will explain the process in detail on our website.
We sincerely apologize to all users and potential purchasers for any inconvenience this issue may cause.
