The DJI Z-Axis for Osmo Pro is an add-on stabilizer accessory for the DJI Osmo Pro Gimbal. Key features include: One More Axis. If the Osmo Pro’s three axes just don’t cut it, why not add a fourth? What you get with the Z-Axis is vertical shake correction, commonly seen in video shot while walking or jogging. Purely Mechanical. Unlike the three-axis correction the Osmo natively performs, this Z-Axis stabilization is all-mechanical. There’s no brushless / electronic motor wizardry going on in there. It’s a spring. Osmo Pro-Specific. This add-on accessory is only compatible with the DJI Osmo Pro Gimbal.
