same here... pretty darn good
but the drone is going to have some high-frequency amplitudes that will intermodulate with the drone's flight amplitudes... and ... it's a guess, but I think it might be difficult... please let us know... I was under the impression that all the stability programs are for the rather slow and heavy-handed amplitudes of humans, not motors...
BTW.. the 55mm 1.8 is a far sharper lens in the center and corners, but no OSS... so if OSS doesn't work, the 55 1.8 is the lens I'd use hands down. It's not that the 24-70 is so poor, it isn't. The 55mm is just that good. As good as a Leica 50mm -cron centrally (and that's very good indeed!). Not quite as good as the Leica in the corners though. Not bad at all, but not quite as good. You can hurt yourself with the sharpness of the -cron... maybe put an eye out...
