I just saw that Gudsen released the Moza Air 2 and it's basically a Ronin S that WORKS with Sony: https://www.gudsen.com/moza-air-2 (not all new models yet, but at least it works & I would assume will be updated to the A73 series.)
So I guess my question, is there any update on the pull focus for Sony? I see the shutter control is being worked on, but I feel like that shouldn't be the top priority for videographers.

Hi zhovisuals, we received many users' request of Sony and this is our development priority, our engineers are still working on developing USB Shutter Control and more features, we will also release Focus Motor Lite in the future, appreciate your patience for the future update very much.
