Tamron 28-75mm f2.8 For Sony Firmware Update To Fix Autofocus Issue

By Wendell Weithers on July 13th 2018

The Tamron 28-75mm f2.8 was a highly anticipated lens that promised a combination of quality and price that has hitherto been absent from Sony’s lens lineup. However, the enthusiasm surrounding the lens was dampened when early reviews began to circulate which revealed a bug in the firmware that caused the autofocus in some lenses to perform poorly.

Although it has stumbled out of the blocks, Tamron is looking to regain its stride and quell any lingering concerns that it’s a viable alternative to Sony’s native glass. In a recent press release it has announced the following:

Dear users and potential purchasers of Tamron interchangeable lenses.
