Dear Tamron product users and potential purchasers.
Thank you for your interest in Tamron products.
We would like to announce that we found an issue with our 28-200mm F/2.8-5.6 Di III RXD (Model A071) for SONY mirrorless cameras.
Under long exposure mode, such as shooting astrophotography or night scape, you may spot a noise at the right edge of the image.
We are currently working on the cause of the error and for the solution to this matter. We expect this issue to be resolved very shortly and we will release a firmware update at that time.
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.
