Tamron "significantly improves" the AF performance of two lenses
A new firmware update from Tamron will boost the autofocus performance in two of its lenses

You may be aware of camera firmware updates, but how many times have you been able to boost the performance of your lenses? Tamron has done just this with a new firmware update for two of its Sony E-Mount optics.
Two Tamron lenses have been given the new update: the Tamron 35-150mm f/2-2.8 Di III VXD and the Tamron 28-200mm F/2.8-5.6 Di III RXD, with both updates exclusive to the E-Mount.
"With this new firmware update, the AF tracking performance has significantly improved, and will now keep good track of a moving object," says Tamron. "Also, AF Assist function during video recording is now supported."
This is not just a firmware update to fix bugs and small issues; this is instead an update that improves the lens performance lens. We have seen this happen recently with camera firmware, but it is also good to know that lens manufacturers keep existing optics up-to-date and future-proof with advances in camera performance.
