Tamron has released a firmware update to address autofocus issues with their new and very popular 28-75mm F/2.8 Di III RXD (Model A036) lens for Sony full-frame E-mount.

Firmware version 2 addresses the following issues in video shooting mode:

1．Autofocusing operation and loss of focus
2．Flicker on peripheral parts of the image when zooming

The update also appears to have fixed autofocus issues whilst shooting stills as well.

You can download the firmware update here.

If you are using MacOS 10.13 (High Sierra) then you will need the DriverLoader 1013 to install this firmware update, otherwise it will most likely fail. Full details are available on Sony’s website.

The 28-75mm F/2.8 Di III RXD lens has certainly proven to be a very popular addition to the gear bag of many Alpha Shooters. With great reviews from all over the web, this lens is currently sold out in most camera stores.

About Timothy Mayo

I love shooting wildlife the most but will happily point my camera at pretty much anything. I started Alpha Shooters in 2017 to share my own photographic journey and experiences shooting with Sony Alpha. The site has since evolved into a popular community and resource. You can also find out more about my story here or follow me on Instagram if you wish. I also have a YouTube Channel but haven't published much content over the past year due to spending more time changing smelly nappies and also launching our community forums. However, I do plan to get back to creating content for YouTube in 2021!
