After returning the Fotodiox smartphone gimbal, I picked up a DJI Osmo. It seemed to have everything I was looking for in one small, compact package. One drawback to the Fotodiox is that it's a simple gimbal -- there weren't any pan/tilt controls, and the DJI offers a lot of cool features like the joystick to pan/tilt while gliding. Additionally, the trigger on the front of the handle can lock orientation for certain shots, and offers a "selfie" mode if you're into that. It also supports external microphones -- which is a good thing, because the internal mic is terrible.
Future-proofing itself, the Osmo X3 camera is removable and replaceable with other cameras that DJI may release in the future. The X5 Micro For-Thirds camera is now available and there is an adapter to allow the use of the X5 camera on the Osmo handle. It's pricey, but it's good to know that the option is available if I decide that this is all I'll be needing for my tracking/steadicam-type shots.
I plan on doing a full review of the DJI Osmo once I can get some hands-on time playing with it and using it on some upcoming gigs. For the time being, here's some quick footage from the DJI Osmo. It's all footage straight from the camera, without any grading or color correction. The newest firmware allows for different camera profiles, allowing for more latency when color correcting, and also improves on the camera's low-light performance, which has been one of the criticisms of the Osmo's camera.
