I've never used a gimbal, but decided to try out the Zhiyun Crane-2 after the new price drop and included servo follow focus. I saw one video showing no functionality between the Crane-2 and 5d3 with Magic Lantern, but was thrilled to find the combo actually works well (at least with the setup described in the subject). Being able to start/stop recording, adjust ISO, shutter speed, aperture, and focus with manual lenses from the crane-2's grip is very convenient. The only downside so far is the weight.
