Indeed ... it's a fair lens, for sure, and the ability to dial in the fov while in the air is great. I can't imagine trying to do a smooth zoom while flying .. well, I guess I could .. in hover ... but more often than not I'm trying to use the flying aspect to change parallax and perspective, rather than fov transition .. could use the smooth zoom more on the Osmo.
I also found that the zoom works smoothly on my osmo X5...really disappointing that it zooms smooth on the osmo and not the inspire but still a useful lens on the bird.
