Tamron’s latest lens hit the market with a lot of fanfare, but AF issues have been reported
Tamron has officially confirmed that they are aware of autofocus issues present in their recently released [amazon_textlink asin=’B07CSLM1X8′ text=’28-75mm F2.8 Di III RXD’ template=’ProductLink’ store=’thephobl-20′ marketplace=’US’ link_id=’bba12412-6502-11e8-a660-3f8ec55df5da’] lens for the Sony full-frame mirrorless ecosystem. The lens was announced back ahead of WPPI to great fanfare along with a ton of other third-party FE lenses. Tamron made it a point to say that their lenses would feature full native functionality on E Mount cameras and that users would be able to expect native lens performance.
So, for AF issues to become apparent after just a short time in the wild, it is a bit of a black mark thereon Tamron’s claims around launch. That said, Tamron has done the right thing here: they have officially announced that they are acknowledging the AF issues users are reporting and that they are currently investigating the issues.
According to the user reports the issues can sometimes present themselves as a complete failure by the camera to achieve accurate focus. Sometimes completely freezing up. Apparently, though, the issue is most prevalent for some reason when users are recording video, though some have also reported it while simply shooting stills.
What is clear from the Tamron announcement is that at this point the company doesn’t know what is wrong; hence the note about “evaluation” of the issue. In other words, they are still trying to figure out what is wrong and how to resolve it. That said, on the bright side, thanks to the open nature of the Sony E Mount system, owners of the lens should be able to simply install a firmware update through the camera to the lens once one is made available by Tamron.
The company says they are confident that the issues will be resolved shortly and that a firmware update will be released once the solution is found and a fix is verified. For more information on the issues or to read Tamron’s full press release you can find everything you need over on their website.
