Leaked images show what I believe to be the X4S equivalent camera for a news Osmo 2 device. The images show a gimbal head similar to that of the Inspire 2 X4S but with a larger camera head. Possibly the device will come with optical zoom as default. This device I think will be the HG910 camera. The gimbal has the same mounting format as the X4S and X5S.
Info is a little thin at the moment but we all know an Osmo 2 is coming, its just a matter of when 🙂
