Tamron will fix the 70-180mm lenses affected by a “floating system” issue
Dear Tamron product users and potential purchasers,
Thank you for choosing Tamron products.
We would like to announce that we found the performance of the floating system which corrects the field curvature may be insufficient (*) in a part of our 70-180mm F/2.8 Di III VXD (Model A056) products for SONY mirrorless cameras.
For affected products, we will inspect them and either readjust or exchange them.

Printed at label on the top of packaging boxWe sincerely apologize to all users and potential purchasers for any inconvenience this issue may cause.
We appreciate your continued support for our products.(*) Supplement of the issue
Model A056 achieves a high optical performance utilizing the aberration correction by the floating system. By optimizing the value for each lens, we can achieve the maximum effectiveness. We found that some lenses have already been shipped out without the value being optimized.【Model A056 Product Page】
