Although Tamron seems to be getting ready to release more lenses, they look like they’re already having a tough time with their existing ones. Not long ago they released an advisory over compatibility between two of their F mount lenses and the Nikon D6. Now another advisory has surfaced for their new 70-180mm f/2.8 Di III VXD lens for Sony E mount.
According to DPReview, a number of lenses were shipped from the factory without proper calibration of the internal floating elements, potentially resulting in a loss of image quality. And this is something that you can’t fix yourself with a firmware update and a dock. You’ll have to send it in to Tamron.
