DJI must have been getting some complaints from Osmo users about the bumpy pictures especially from a walking point of view so for an extra £110 you can add the Z-Axis making it a smooth as steadycam.
Battery power is limiting but I have three in my kit which is more than I ever need in a days shoot, remembering you don’t use the Oslo constantly during a shoot.
People complain about the sound from the Osmo which is fine as long as you take it away from the Osmo itself i.e. Via a radio mic. Watch my edited review on the JVC-LS300 Firmware update to see the Osmo used with a radio mic (Rt 3.25s). You can also see how the Osmo worked before the Z -Axis was installed.
