I know a lot of people were waiting for this, and it's finally here - the official DJI OSMO X5 Adapter to (properly) mount that Mirrorless X5 Interchangeable Lens camera.
This is pretty big news for those looking for the smallest combination of ILC and 3-Axis Gimbal. But with a bigger camera this means shorter battery life. So DJI has also announced an OSMO external battery extender. The battery extender allows for a DC input, or you can get an optional cable to connect directly with one of your DJI Drone batteries.
And for active shooting to where you need additional stabilization on vertical movements (up/down running, jumping, car mount, etc), they've added a Z-Axis arm accessory that works like a mini Steadicam ISO Arm.
DJI has certainly thought of just about everything, but the X5 camera isn't cheap (unless you already have an Inpsire1 Pro). The X5 is a micro four-thirds camera and starts at $1699 (here).
And just in case you're not familiar with the DJI OSMO, here's an introductory video showing the basic version with the entry level X3 camera.
Of course you can improve the OSMO system greatly by adding some of the new accessories and camera mentioned in this article.
