Our Firmware Friday roundup this week is brief, with news of just two new firmware releases in the past seven days. Both come from Sony for its E-mount lenses.

So what's new in the firmware for the Sony FE 100–400 mm G Master and FE 70-200 mm F2.8 GM OSS lenses? Both updates make the exact same change, improving continuous autofocus performance during zoom operation when shooting using a Sony A9 camera body (So if you don't have a Sony A9, you can safely defer the update for the time being.)

You can download the new firmware at the links below:

And that's all for this week. Be sure to check back news time for more firmware news!
