Support is initially limited to the A7R IV and A9 II, but should “gradually” include more models. Sony hasn’t indicated everyone who’s interested, although camera robotics and control specalist Telemetrics is eager to put the SDK to work.

To some extent, Sony didn’t have much of a choice but to open its platform. It’s increasingly gunning after pro photographers who would otherwise choose Canon and Nikon gear, and that means supporting real-world workflows instead of insisting on as many Sony tools as possible. No, you probably won’t notice if you’re a hobbyist or street photographer, but this could make all the difference in some fields.
